Analog Devices, Inc. (Nasdaq: ADI), a global semiconductor leader, and Seeing Machines (LSE:SEE), an advanced computer vision technology company that designs AI-powered operator monitoring systems to improve transport safety, announced a collaboration in support of high-performance driver and occupant monitoring system (DMS/OMS) technology.

Long-haul driving and congested traffic are two scenarios where driver fatigue and distraction often occur and frequently cause accidents, resulting in injury or worse. New and sophisticated advanced driver assistance systems (ADAS) are rapidly evolving to support safety across increasing, varied levels of autonomous capability.

The collaboration pairs ADI’s advanced infrared driver and high-speed Gigabit Multimedia Serial Link™ (GMSL) camera connectivity solutions with Seeing Machines’ artificial intelligence (AI) DMS and OMS software to support powerful eye gaze, eyelid, head, and body-pose tracking system technology that more accurately monitors driver fatigue and distraction. The combined solution will readily meet European Commission General Safety Regulations (GSR) and European New Car Assessment Program (Euro NCAP) requirements. It is also conducive to enabling future occupant monitoring features and a range of in-cabin camera placement options, previously unworkable due to challenges related to power efficiency, functional safety, hardware footprint, and image quality.

Semi-autonomous driving systems rely on in-cabin DMS and OMS to recognise and address driver fatigue and distraction. These systems must operate in all lighting conditions and require proper infrared lighting to ensure image quality on a frame-by-frame basis necessary for eye tracking in real time. The combined solution from ADI and Seeing Machines leverages ADI’s industry-first infrared driver for DMS and OMS, capable of delivering up to 100W of peak power in a compact and functionally safe solution. This allows for a non-intrusive, smaller camera module in a vehicle’s cabin.

Seeing Machines’ AI software interprets signals from the optical hardware, monitors and diagnoses the problem, and combines with ADAS features to enable output signals to warn drivers and vehicle occupants when necessary.

“Seeing Machines exists to get people home safely, and our work with ADI aims to support semi-autonomous driving with increased safety levels to deliver what we call ‘supervised automation’,” said Nick DiFiore, SVP and GM of Automotive at Seeing Machines. “ADI’s proven automotive-grade, near-infrared drivers and GMSL devices enable a sophisticated optical path to provide critical illumination and high-speed video bandwidth for real-world and real-time processing of interior cabin environments.”

“Cabin monitoring is complex and requires careful integration of infrared illumination, image capture, data processing, and algorithm layers to achieve a real-time response,” said Yin Wu, Director of Automotive Product Line Management at Analog Devices. “Together with Seeing Machines, we are supporting the automotive industry with pragmatic solutions to help reduce collisions and save lives.”

ADI’s MAX25614 IR LED driver and GMSL serializer and deserializer (SerDes) connectivity solutions are supporting Seeing Machines’ FOVIO DMS and OMS solutions.

Pricing and Availability

Widening prosperity is combining with the proliferation of sensors and extensive cloud connectivity to accelerate the pace of change in factory systems and equipment.

The way in which factories operate is changing fast in the face of powerful economic and technological forces. The most agile factory equipment manufacturers will thrive in this fast-changing environment, as they develop increasingly connected and intelligent systems which help factories become more flexible and safer, while maintaining security as they extend connectivity. Increased use of automated and autonomous systems will reduce factories’ dependence on labour for repetitive or intricate manual operations.

Semiconductors will be at the heart of this new generation of industrial automation equipment, providing the processing, control, and sensing functions required to operate effectively in connected environments.

Analog Devices (ADI), which has always thrived at the intersection of the analogue and digital worlds, has a close-up view of the technological changes that new factory automation equipment calls for. Its expertise in the fields of sensing, signal conditioning, digital signal processing, wired and wireless connectivity, and software bring it close to the challenges that its industrial customers face, enabling it to develop application-oriented solutions that accelerate OEMs’ time to market. ADI’s goal is to help customers innovate through technology and be prepared for whatever the future brings, while continuing to support legacy systems by providing guaranteed long-term availability of industrial parts.

What the future brings is profound disruption, which has its roots in a welcome trend: the global spread of prosperity.

Widening Prosperity

This century has seen a notable rise in disposable incomes in parts of the world that have traditionally been regarded as developing countries. As a result, demand for manufactured goods is growing globally, putting pressure on manufacturers to expand production while supplying an increasingly diverse set of product configurations, in order to satisfy regional and national variations in demand.

At the same time, the global growth in prosperity is shrinking the availability of cheap, unskilled manual labour. The one-time boost that manufacturers have gained in the past 30 years from off-shoring production to low cost locations such as China is evaporating, as wages in these locations rise, and the workforce, now increasingly well-educated, loses its appetite for performing repetitive manual operations for low pay. In the future, manufacturers will be seeking to increase competitiveness by deploying automation technology rather than moving to a new low cost location.

The Smart and Connected Factory

New technological capabilities are also helping manufacturers gain additional value from expenditure on factory automation equipment.

A proliferation of miniature, high performance semiconductor sensors alongside pervasive connectedness are creating a deluge of data on machine and process performance. There is now more potential than ever for rich, new applications of data analytics, such as machine health monitoring and preventive maintenance. At the same time, the increasing use of programmable hardware and software-defined electronics functions enables rapid reconfigurations of factory processes and tools.

The factory of tomorrow, then, will be more agile and responsive to demand, more automated, and more reliable. It will require fewer human operators and will face less disruption due to unplanned maintenance.

So which technologies in the analogue and digital semiconductor worlds are going to enable this new model of factory automation?

Sensors - The Key to Machine Health Monitoring

MEMS sensor technology is enabling the development of new sensor types that are small, robust, and able to precisely measure vibration and motion. For instance, low noise, wide-bandwidth accelerometers offer the high precision and accuracy required to identify subtle changes in the vibration signature of a machine. Coupled with sensor analytics software, these devices enable equipment operators to pinpoint the source of a potential failure long before it occurs and apply preventive maintenance measures in good time.

Machine health monitoring is an application that is not confined to conventional factory settings. Mobile or remote industrial equipment may use a wireless connection to report diagnostic information and operating status to a central controller. Running on battery power or intermittent power sources such as solar energy, this kind of application requires a very low power sensing solution.

High Speed Connectivity on the Factory Floor

The proliferation of sensors throughout factories and process plants is generating vast flows of real-time data. Legacy communication protocols between sensor nodes and PLCs, such as 4mA to 20mA control loops, are giving way to ultrafast industrial variants of the Ethernet protocol, enabling increasing integration of operational technology (OT) infrastructure in the factory with information technology (IT) in the enterprise.

In responding to this new demand for high speed data transfer in the factory, OEMs need to future-proof their system implementations, so that they support not only industrial Ethernet protocols in use today, but also the emerging time-sensitive networking (TSN) variant of Ethernet, which is likely to become the standard wired networking technology for real-time industrial communications. To support this transition, ADI provides an Ethernet platform which enables systems to swap from one Ethernet protocol to another without the need for hardware redesign.

Robust, wireless sensor network technologies are also required for connecting sensor nodes in locations that are hard to reach with physical wiring. Wireless network technologies such as SmartMesh® and WirelessHART, which are designed to operate in tough IoT applications, provide a proven and high performance method of connecting industrial automation equipment without wires.

Safety Systems for Autonomous Machines

Autonomous vehicles and cobots offer a huge scope for widening the application of automation in factories and warehouses. The challenge for industry is to guarantee safety, ensuring that autonomous machines are fully environment-aware. Advanced radar and lidar technologies are raising the standard of accuracy and precision in object and proximity detection and 3D mapping applications.

Protecting the Factory from Online Attack

With the growth in connectivity comes a heightened risk of attack by hackers intent on extorting payment from factory operators, or by state-sponsored attackers tasked with causing disruption to high value industrial systems.

As factory operators connect more and more nodes to the cloud, they open up new entry points for hackers to exploit. Semiconductor-based connectivity systems need robust security optimised for embedded systems. Analog Devices is developing new solutions to meet emerging security threats to industrial systems, thus helping to future-proof customers’ industrial infrastructure.

Configurable Production Processes

The factory of the future must be capable of quick adaptation to new demands and new workflows; the key is to build flexibility into industrial automation technology products at the architecture level. One approach which can support this need for flexibility is software-defined I/O, which can be configured as analogue or digital, and input or output, without altering wiring.

Pushing the boundaries of today’s technology, ADI already supplies a robust and flexible industrial output solution, which enables full software configurability of the analogue output to support a variety of industrial standards.

Integrating Analogue, Digital, and Software

The development and production of industrial automation equipment is becoming an increasingly high tech undertaking, driven by the need to meet end user demand for higher throughput, more configurability, safer operation, and more cloud integration. At the same time, pressure to get to market quickly with new, more sophisticated designs continues to intensify.

Analog Devices’ response is to provide customers with an integrated offering, providing market-oriented solutions for applications including, among others, machine health monitoring, high speed connectivity, and safety and security systems. It will do so by combining analogue, mixed-signal, and digital components with firmware and software to solve the most pressing development problems that its customers face, enabling them to respond rapidly and effectively to the intensifying technological and economic challenges of today and tomorrow.

The future of 48V/12V battery systems in automobiles is just around the corner. Most of the major automobile manufacturers across the globe have been working on proving out their systems for the past few years and it is evident that their implementation will be relatively near term. This is a necessary and crucial step in the long and arduous journey to the fully autonomous passenger vehicle that does not require a human at the controls and has true autonomous driving. Nevertheless, this doesn’t mean the 12V battery is going away; there are far too many legacy systems in the installed vehicle base for this to occur. This means that autonomous cars will have both a 12V battery and a 48V battery.

This fact means that the vehicles’ internal systems will either run off the 48V lithium-ion (Li-Ion) battery or the 12V sealed lead-acid (SLA) battery - but not both. Nevertheless, in addition to having two separate charging circuits for these individual batteries due to their respective chemistries, there must also be a mechanism that allows charge to move between them without causing any damage to the batteries or any of the systems within the vehicle. Moreover, having two batteries also allows for redundancy should one of them fail during operation.

While this certainly complicates the design of the various electrical subsystems within the vehicles, there are some advantages to be gained. According to some auto manufacturers, a 48V-based electric system results in a 10% to 15% gain in fuel economy for internal combustion engine vehicles, thereby reducing CO2 emissions. Moreover, future vehicles that use a dual 48V/12V system will enable engineers to integrate electrical booster technology that operates independently of the engine load, thereby improving acceleration performance. Such compressors are already in the advanced stages of development and will be placed between the induction system and the intercooler, using the 48V rail to spin-up the turbos.

Globally, fuel economy regulations have been tightening, while autonomous driving capability with connectivity continues to proliferate in new automobiles. Accordingly, the 12V automobile electric system has reached its usable power limit. Simultaneously, as if these changes are not already enough, there has been a significant increase in automotive electronic systems. These changes, coupled with related demands for power, have created a new spectrum of engineering opportunities. Clearly, the 12V lead-acid battery automotive system with its 3kW power limit must be supplemented.

Furthermore, there are new automobile standards that impact how these systems need to work. The automotive standard, known as LV 148, combines a secondary 48V bus with the existing automotive 12V system. The 48V rail includes an integrated starter generator (ISG) or belt start generator, a 48V Li-Ion battery, and a bidirectional dc-to-dc converter, which can deliver tens of kilowatts of available energy from the 48V and 12V batteries. This technology is targeted at conventional, internal combustion automobiles, as well as hybrid electric and mild hybrid vehicles, as auto manufacturers strive to meet increasingly stringent CO2 emission targets.

New Power Solution for 48V/12V Battery Systems

This new standard requires the 12V bus to continuously power the ignition, lighting, infotainment, and audio systems. Whereas, the 48V bus will power active chassis systems, air conditioning compressors, adjustable suspensions, electric superchargers, turbos, and even regenerative braking.

The implementation of an additional 48V supply network into vehicles is not without significant impact. Electronic control units (ECUs) will be affected and will need to adjust their operational range to the higher voltage. This will necessitate that manufacturers of dc-to-dc converters will also need to introduce specialised ICs to enable this high power transfer.

Accordingly, Analog Devices’ has designed and developed a few dc-to-dc converters that can enable this energy transfer with very high efficiency to conserve energy while simultaneously minimising the thermal design aspects.

The need for a bidirectional step-down and step-up dc-to-dc converter that goes between the 12V and 48V batteries is clearly required. Such converters could be used to charge either of the batteries while simultaneously allowing both batteries to supply current to the same load if required in the system. From a legacy perspective, these initial 48V/12V, dual battery, dc-to-dc converter designs used different power components to step-up and step-down the voltage.

Analog Device’s LT8228 is a bidirectional dc-to-dc controller that uses the same external power components for step-up conversion as it does for step-down conversion. This device is a 100V bidirectional constant-current or constant-voltage synchronous buck or boost controller with independent compensation networks. The direction of the power flow is automatically determined by the LT8228 or is externally controlled. The input and output protection MOSFETs protect against negative voltages, control inrush currents, and provide isolation between terminals under fault conditions such as switching MOSFET shorts. In step-down mode, the protection MOSFETs at the V1 terminal prevents reverse current. In step-up mode, the same MOSFETs regulate the output inrush current and protect themselves with an adjustable timer circuit breaker.

Furthermore, the LT8228 offers a bidirectional input and output current limit as well as independent current monitoring. Masterless, fault-tolerant current sharing allows any LT8228 in parallel to be added or subtracted while maintaining current sharing accuracy. Internal and external fault diagnostics and reporting are available via the fault and report pins. The LT8228 uses a 38-lead TSSOP package.

The LT8228 is a 100V, bidirectional, peak current-mode synchronous controller with protection MOSFETs. The controller provides a step-down output voltage, V2, from an input voltage, V1, when in buck mode or a step-up output voltage, V1, from an input voltage, V2, when in boost mode. The input and output voltage can be set as high as 100V. The mode of operation is externally controlled through the DRXN pin or automatically selected. In addition, the LT8228 has protection MOSFETs for the V1 and V2 terminals. The protection MOSFETs provide negative voltage protection, isolation between the input and output terminals during an internal or external fault, reverse current protection, and inrush current control. In applications such as battery backup systems, the bidirectional feature allows the battery to be charged from either a higher or lower voltage supply. When the supply is unavailable, the battery boosts or bucks power back to the supply.

To optimise transient response, the LT8228 has two error amplifiers: EA1 in boost mode and EA2 in buck mode with separate compensation pins VC1 and VC2, respectively. The controller operates in discontinuous conduction mode when reverse inductor current is detected for conditions such as light load operation. The LT8228 provides input and output current limit programming in buck and boost mode operation using four pins: ISET1P, ISET1N, ISET2P, and ISET2N. The controller also provides independent input and output current monitoring using the IMON1 and IMON2 pins. Current limit programming and monitoring is functional for the entire input and output voltage range of 0V to 100V.

Furthermore, the LT8228 provides masterless, fault-tolerant output current sharing among multiple LT8228s in parallel, enabling higher load current, better heat management, and redundancy. Each LT8228 regulates to the average output current eliminating the need for a master controller. When an individual LT8228 is disabled or in a fault condition, it stops contributing to the average bus, making the current-sharing scheme fault tolerant.

Additional features include:

1. Feedback voltage tolerance: ±0.5% over temperature
2. Bidirectional programmable current regulation and monitoring
3. Extensive self-test, diagnostics, and fault reporting
4. Programmable fixed or synchronisable switching frequency: 80kHz to 600kHz
5. Programmable soft start and dynamic current limit
6. Masterless, fault-tolerant current sharing

Conclusion

The LT8228 brings a new level of performance, control, and simplification to 48V/12V, dual battery, dc-to-dc automotive systems by allowing the same external power components to be used for step-down and step-up purposes. It operates on demand in buck mode from the 48V bus to the 12V bus or in boost mode from 12V to 48V. When starting the car or when additional power is required, the LT8228 allows both batteries to supply energy simultaneously to the same load. This gives power conversion designers a feature rich, bidirectional converter that can easily configure 12V and 48V battery systems, which will be required for the fully autonomous vehicles of the near future.

ADI’s industry-first matrix LED driver enables local dimming to enhance the in-cabin experience while improving power and safety

Analog Devices, Inc. (Nasdaq: ADI) has announced that AUO Corporation (TPE: 2409) will use ADI’s matrix LED display driver technology in their market-leading automotive widescreen display portfolio. This industry-first technology enables local dimming, significantly improving power consumption by a minimum of 50% and supporting functional safety requirements.

To deliver a more immersive experience, vehicles are incorporating widescreen displays throughout the cabin. Increased automation and autonomy are pushing the requirements of these displays from a typical infotainment hub to a safety centre with visuals surrounding the vehicle. Furthermore, the automotive industry is accelerating the transition to electric vehicles, where power consumption is increasingly important.

To meet these requirements, ADI has developed a unique approach called local dimming that drives LEDs behind the screen in the car display unit. Developed through a proprietary power process technology, the driver integrates all external switching positive channel field effect transistors (PFETs), enables high resolution and high contrast ratio for large automotive displays, provides improved diagnostics of LEDs, and reduces ghost images. The system reduces power consumption by a minimum of 50% compared to the traditional edge lit display. ADI’s power portfolio is ASIL-B to D rated, a critical consideration for many automotive manufacturers that require functional safety features to ensure reliable operation within the vehicle.

ADI aims to enhance the in-cabin experience by enabling energy-efficient widescreens capable of local dimming through proprietary power management and processing solutions, as well as high resolution displays through Gigabit Multimedia Serial Link™ (GMSL) serialiser and deserialiser (SerDes) connectivity solutions.

“To help us maintain our leadership position in the market as one of the world’s top automotive display manufacturers catering to some of the largest OEMs, ADI's local dimming automotive display drivers deliver the power efficiency consistent with the quality standard of the AUO brand,” said Simon Hsu, Head of Automotive Business Unit at AUO. “AUO AmLED displays feature power savings, excellent sunlight readability and high contrast ratio, which greatly upgrade driving safety and in-cabin entertainment experience. In response to the trend of smart mobility, AUO continues to advance display technology, and we look forward to further collaborations with the ADI team.”

What are the markets of interest for Analog Devices and what is ADI’s current offering?

Analog Devices (ADI) is a semiconductor manufacturer and solutions provider for several industry markets. We have five target markets: industrial, communications, automotive, consumer, and medical. The medical market can be divided into several subsegments. These include medical imaging, vital sign monitoring (VSM), and medical instrumentation. We are active in every subsegment where market demand typically varies by region and due to geographical location. Noticeably, over the last couple of years, VSM has been one of the fastest growing segments in every region.

Ten years ago, VSM applications were mainly found in hospitals and professional rescue units such as ambulances and helicopters. The biggest market was for bedside monitors and monitors in intensive care departments. These high-end systems support multilead ECG measurements, oxygen saturation, body temperature, and CO₂, and measure several other parameters. Now, VSM is becoming a part of our day-to-day lives. Wearable VSM systems make it possible for physicians to remotely monitor their patients. Instead of recovering from a surgery in the hospital, patients can be discharged sooner and recover in the comfort of their home. This not only helps reduce costly medical expenses but can also improve recovery time as recovery is often quickened in a private environment. Remote VSM systems can also allow elderly people to live independently for a longer time. With the aging population, elderly care houses are becoming unaffordable, so a remote monitoring system enables fewer professionals to monitor a bigger group of people. VSM for sports and exercise is trending as well. This helps people not only monitor their vital parameters, but also shows feedback on whether the exercise is effective.

Can you speak about ADI’s portfolio of sensors and how easy it is to integrate them into a device?

The market has changed rapidly. ADI used to make individual building blocks for signal conditioning and conversion into the digital domain. Now we support complete analogue front ends that include everything from the analogue input stage up to the digital interface, including self-calibration and temperature compensation. We also include the sensor element where possible, so we now have single chip solutions for biopotential measurement, bioimpedance sensing, optical PPG measurement (for heart rate, heart rate variability, and SpO₂ monitoring), motion tracking, and accurate body temperature sensing. All these subsystems have integrated ADCs, so it is very easy to measure a certain parameter and include the measurement readings in your final application or system without the need for building a complex circuit diagram with discrete components.

Optical sensors make it possible to measure heart rate at a single spot on the body, but you can also measure heart rate variability (a measure for stress level detection) or oxygen saturation (the percentage of red blood cells carrying oxygen). We started with discrete amplifiers to interface photodiode currents, followed by analogue front ends, conditioning the photocurrents, and then integrated current sources to control the LEDs used for controlling the light emitted in the system. Because not every electronic engineer is an optical engineer, we developed a half-dozen optical modules. These modules combine the analogue front end, one or more photodiodes, and the required LEDs to support a complete optical system. These are very small and optimised to reduce time to market and cost in this very competitive market.

What are your latest solutions in the field of healthcare?

With reference to our latest introductions, we recently launched a biomedical analogue front end called ADPD4000. In a wearable device, you often measure more than just one parameter, such as heart rate, activity, skin impedance, oxygen saturation, and body temperature. Why would you use an individual chip or sensor for every measurement? Doing so would increase the overall board size, the required power, and, certainly, the overall system cost. The latest introduction makes it possible to do all these measurements, with exception of motion, with just one chip. The chip directly connects to biopotential electrodes to measure cardiac signals. It’s able to measure galvanic skin response for stress or mental state tracking. It has eight inputs to measure photocurrents and eight current sources to drive LEDs. In addition, the chip supports auxiliary inputs to measure capacitance and temperature. With a chip like the ADPD4000, you can build a wearable VSM system that’s very power efficient, small, and cost-effective.

How has this changed the way our health is monitored in the last years?

The medical market used to be doctor-centric, meaning that we used to only visit a doctor when not feeling well or for a more obvious health problem, for example, after having an accident. Technology - and especially the electronic industry - has had a big impact on the overall healthcare market while creating a more patient-centric approach. We, as the consumer (or patient), have more options on how to monitor our health conditions and where to go for our healthcare and medical services. While having access to wearable devices, we can monitor important vital parameters on a daily basis and are able to detect changes or anomalies at a much earlier stage compared to the past when we only recognised an issue when it impacted our well-being. The advantage of monitoring our parameters and detecting anomalies at an earlier stage is that we can start the treatment of certain diseases before they progress and cause permanent damage to the body.

As an example, there are many people suffering from hypertension, which is also known as high blood pressure. In some situations, this is a well-known issue; however, there are also many occasions where hypertension isn’t causing any visible symptoms. Over a longer period, this high blood pressure can result in either stroke, heart failure, arterial fibrillation, or several other risky diseases. Hypertension can be treated very easily by lifestyle changes and medication to reduce the risk of health complications. Wearable devices that are monitoring critical vital parameters can frequently save lives or prevent health events that may lead to permanent damage.

Another good example where wearable devices can improve lives is for those who suffer from diabetes. Depending on the severity, diabetics must monitor their glucose levels a few times per day and rely on taking insulin to regulate glucose levels. Though most diabetics may become accustomed to this over time, it can be an inconvenient and burdensome disruption to daily life. There is a new trend, now moving from the blood glucose monitoring (BGM) approach toward a continuous glucose monitoring (CGM) system, which is made possible by wearable sensing technology. With this technology, glucose levels can be measured continuously throughout the day, while an insulin pump injects the required insulin in order to stay in range. As this will be a closed-loop approach, the burden is lifted from the consumer (or patient). This will have a big impact on daily life, providing freedom from the disruption that diabetics so often deal with. Technology - and especially wearable devices - is proving to have invaluable benefits, both in terms of preventative measures or for those that are already diagnosed with a well-known disease.

Analog Devices is working on many sensors and sensor solutions for the medical market that will help to improve our quality of life. When you would like to learn more, please have a look at analog.com/healthcare.

USB Type-C is a relatively new, high power USB peripheral standard used in computer and portable electronic devices. The USB Type-C standard has driven changes in the USB power delivery specification, allowing for increased bus voltages (up to 20V) and current delivery capability (up to 5A) from the long-standing 5V USB standard. Connected USB-C devices can recognise each other and negotiate a bus voltage - from the default 5V USB output to several higher preset voltage steps - for faster battery charging and higher power delivery where needed, up to 100W.

The simple, compact buck regulators and linear regulators used in battery chargers that require only USB 5V at 500mA to 2A do not sufficiently cover the full range of Type-C USB power. The increased voltage range, 5V to 20V, of Type-C USB power delivery requires more than just step-down voltage conversion from 9V to 36V (or 60V) automotive batteries, or other charging sources. An adjustable buck-boost converter is needed with the ability to both step-up and step-down the input-to-output voltage.

Additionally, for high power automotive USB chargers, a buck-boost converter should support a 10A or higher peak switch current rating and offer low EMI performance. The ability to set the switching frequency outside the AM radio band and maintain a small solution size are sought-after features. High voltage monolithic converters (with onboard switches) are not capable of sustaining such high peak switch currents without burning up.

The LT8390A is a unique 2MHz, synchronous 4-switch buck-boost controller. At 2MHz switching frequency, it can deliver output voltages between 5V and 15V (up to 45W at 3A) to provide power to a connected USB-C device from a car battery. This high controller switching frequency keeps the solution size small, the bandwidth high, and the EMI outside of the AM radio band. Both spread spectrum frequency modulation and low EMI current-sense architecture help LT8390A applications pass the rigors of the CISPR 25 Class 5 automotive EMI standard.

High Power Density Conversion: Size (and Power), Efficiency, Heat

The design of a voltage regulator system operating in an automotive or portable electronics environment is constrained by the space required for the circuit, as well as the heat it generates during operation. These two factors impose an upper bound of achievable power levels while operating within the given design constraints.

Increasing the switching frequency of a design allows for the use of smaller inductors, which is often the largest footprint component in wide input voltage 4-switch buck-boost voltage regulator designs. The LT8390A’s 2MHz switching frequency capability enables the use of a much smaller inductor size than a 150kHz or 400kHz design. A complete design is shown in Figure 1. Along with a smaller inductor, this solution uses only ceramic output capacitors, eliminating the need for bulky electrolytic capacitors. All the components necessary for this design, including the IC, are contained within a small, 1" inch square footprint.

Low EMI for Automotive Applications

The LT8390A has several unique EMI mitigating features that enable high power conversion with low noise performance, which simplifies its implementation in automotive systems. A notable difference between LT8390A and alternative 4-switch controllers is the placement of the inductor current sensing resistor. Most 4-switch buck-boost controllers tend to use a ground-referred current sensing scheme to obtain switch current information, whereas the LT8390A places its current sense resistor in-line with the inductor. By placing the sensing resistor in-line with the inductor, it is effectively removed from both the buck and boost hot loops, shrinking the loops in size and improving the EMI performance.

Along with the architectural advantage of the inductor sensing resistor placement, the LT8390A has built-in spread spectrum frequency modulation to further reduce EMI generated by the controller. Furthermore, the switching edge rate is controlled on both the buck and boost power switches using only a few discrete components to slow the turn-on of the MOSFETs, ensuring the proper balance of high frequency EMI reduction and temperature rise in the power switches. With these EMI-reducing features, the only filtering needed to meet CISPR 25 compliance is taken care of by small ferrite filters on the input and output rather than large ferrite cases and bulky LC filters. 

Seamless Output Voltage Transitions

The LT8390A’s output voltage can be adjusted without shutting down the converter by using logic-level signals to drive MOSFETs that adjust the resistor divider off the output to change the set voltage. A USB PD source controller device with GPIO pins can be used in conjunction with the LT8390A system to facilitate the negotiation process between host and USB-connected device and to set the desired bus voltage.

Figure 5 demonstrates how smoothly the output of the LT8390A system transitions from one output voltage to another. When powered from a 12V input source, each transition to an increased output voltage takes at most 150µs to settle, as measured from the rising edge of the digital control signal. During these changes in the output voltage, the buck-boost controller goes through mode transitions - between buck, boost, and buck-boost operation - depending on the relation of input to output voltages. These mode transitions are performed in a controlled manner, preventing excessive overshoot or sagging of the output voltage.

Expanding Beyond 45W

To push the output power level beyond 45W requires operating at a lower switching frequency to reduce switching losses, which might otherwise thermally stress the MOSFETs at this power level. As an alternative to the LT8390A, the LT8390 operates between 150kHz and 600kHz with the same feature set as LT8390A - allowing low EMI, high power buck-boost designs. A 400kHz LT8390 system, utilising a larger inductor and output capacitor, easily achieves 100W of output power from an automotive battery input with acceptable temperature rise. 

Conclusion

The new USB standard for voltage regulators powering connected devices permits higher power transfer by increasing the output voltage range and current delivery that regulators can provide. Portable and automotive battery-powered USB-C charger devices require a wide VIN/VOUT buck-boost regulator to deliver a bus voltage above or below the input voltage. The LT8390A provides up to 45W of output power in a small footprint, made possible by its 2MHz switching frequency. For power levels exceeding 45W, the LT8390 can be used with a slightly larger solution size and lower switching frequency.

Given the explosive growth in the number of things in the Internet of Things, it’s imperative to examine the internet that will connect and enable communication among all the things. Creating reliable wireless connectivity among these devices is proving to be one of the great challenges in IoT. The reliability of the communications system can be defined by the performance of two critical components: a radio transceiver and communications microcontroller. This article discusses how components and solutions from Analog Devices can maximise system-level reliability, enabling high impact applications where the quality, integrity of data, and insights are mission critical.

What’s Good Now Is Not Good Enough

Existing wireless connectivity technologies for consumer devices do not always satisfy the performance demands of industrial and healthcare systems. The different priorities in these systems - including safety, accuracy, and time sensitivity - heighten the need for increased reliability. Cellular systems come close to this but are often unsuitable in terms of battery, cost, and data throughput requirements. Extremely reliable systems exist today for niche industrial and military applications. However, these are designed with reliability being the top priority, and cost appearing further down the list. With industrial IoT, the challenge becomes delivering the same high level of reliability at a much lower system cost.

Let’s consider some scenarios where wireless capability has been added to enhance the effectiveness of a system, and where reliability of connectivity can be mission critical.

Smart Factory: Production Process Control for Industry 4.0

A key attraction of connected devices in manufacturing includes the potential for yield improvements. To achieve this, it is often necessary to gain remote control of various devices in the production chain to implement adjustments. An example is a control valve for a boiler operating in a chemical production process. Immediate, autonomous control of this valve can make real-time adjustments, based on feedback from other stages in the process, leading to more optimised overall efficiency.

Smart Healthcare: Vital Signs Monitoring

Hospitals and care centres are looking to wireless connectivity to monitor patient vital signs. Clunky wired solutions can be replaced with wireless sensor patches connected through a local gateway. Such systems enable more effective patient monitoring while reducing the burden on healthcare staff.

Smart City: Event Sensing for Emergency Response

With advanced image and acoustic sensing and processing methods, systems mounted in public spaces, such as on lamp posts, can detect events such as vehicle accidents and criminal activity with a high degree of confidence. This information can be relayed via wireless communications to the appropriate agency or unit, along with the location information to enable faster emergency response.

Key Challenges in Building Reliable Wireless Connectivity in Complex Environments

RF Obstacles Cause Missed Packets

Each of the examples previously mentioned are subject to distinct environmental challenges that can negatively impact wireless communication. The steel construction and thick walls of factories create large obstacles that can degrade the power of an RF signal to the point where it cannot be received by the target device. The receiver sensitivity of the radio used in the target device will determine how much signal degradation can be tolerated. As little as 2dB change in sensitivity could be the difference between the successful or unsuccessful reception of a signal. Communication system designers must pay close attention to receiver sensitivity when selecting a radio.

Crowded Frequency Bands Cause Missed Packets

Connected devices will typically operate in the relevant ISM band for that region. ISM bands are license free and can be used for a wide range of applications requiring wireless connectivity. 2.4GHz is standardised globally and is widely used by Wi-Fi and Bluetooth® devices. There is also ISM spectrum available in sub-1GHz bands. These bands are commonly used for IoT applications. The band is centred at 868MHz in Europe and 915MHz in the U.S. A challenge arises when multiple devices located in close proximity are sharing the same ISM band. Transmitting devices can interfere with nearby receiving devices, such as in public hospitals, where there are a wide variety of machines sharing the same ISM band. The ability of a radio to operate in the presence of such interferers is measured by the blocking specification. The challenge extends beyond devices operating within the ISM band. Without sufficient blocking capability, mobile phones or tablets operating nearby could cause a loss of communication in the system. In military and aerospace applications, very costly components are used to mitigate the effect of interferers. Radios being used for mission critical data, such as the applications previously mentioned, must achieve similar performance to military and aerospace without incurring the high cost of additional external components. Such radios will continue to receive messages with multiple interferers operating nearby.

Environmental Effects Degrade Performance

Radio transceivers are built on processes that are prone to variations in performance, depending on the environment in which they’re operating. Some variations include temperature changes, voltage supply reductions as batteries discharge, and silicon manufacturing variations across devices. These real life events can cause changes in the operating stability of the device. Let’s look at an event sensing emergency response system operating on a street light. Cold winter temperatures could cause the output power of a device to vary or the receiver sensitivity to degrade. This can cause loss of communication under certain conditions. While this is less of a concern for a consumer device, which is rarely used in such extreme conditions, it would be unacceptable for an emergency response system. At best, the cost is reputational damage to the end product and a service call to replace the faulty device. System designers must ensure that the components selected for the sensing and communication system are robust over changing environmental conditions.

Corrupted Memory Can Lead to Unexpected Outcomes

Reliability is also a concern on the communications microcontroller. Although extremely reliable, both flash and non-volatile memory can occasionally become corrupted. This can occur as a result of unintended effects caused by the operating environment or intentionally through malicious hardware hacking. Regardless of the mechanism, it is imperative that microcontrollers are equipped with the necessary integrity features to identify when a device has been corrupted. Once identified, the microcontroller can either correct the error or shut the device down, appropriately ensuring that the security of the wider system is not breached.

Analog Devices - Designing for Reliability

Analog Devices has been designing robust solutions for over 50 years that deal with these challenges. The requirement of hyper robust systems for industrial IoT is not a new one. The ADF7030-1 ultralow power, sub-GHz ISM band radio and the ADuCM3029 Cortex®-M3 microcontroller, target performance levels and functionality features that enable the most robust communication links.

The ADF7030-1 is the industry’s leading radio for receiver sensitivity performance. In many cases, the ADF7030-1 will be capable of receiving radio signals 3dB below the power of other radios. This means signal strengths of less than half the power of its competitor can still be received.

With industry-leading blocking numbers in excess of 100dB, the ADF7030-1 can achieve a level of interference resilience comparable to military and aerospace equipment, without the need for additional costly external components. This increases value and ensures communication is maintained in the noisiest RF environments.

Through generations of collaboration with leading industrial manufacturers, Analog Devices has well developed methods for coping with real life environmental effects on radio transceivers. As an example, the output power transmitted by a device using the ADF7030-1 varies by less than 0.2dB over the full temperature operating range. This was achieved through radio design methods unique to Analog Devices. Competing radios will vary by up to 2dB.

The ADuCM3029 is designed with flash and ECC parity checks to ensure errors due to memory corruption are identified and corrected where possible. The ADuCM3029 is also equipped with battery monitoring capability in sleep mode. This ensures that unexpected drops in voltage can be detected and the processor alerted to a possible malicious threat or power supply malfunction. The end device can then take appropriate action by either alerting an administrator, or entering a safe mode to ensure the wider system is not compromised.

Technologies developed by Analog Devices inhabit every stage of the IoT signal chain from sensing and measuring, to interpreting and connecting the data. Ensuring the quality and integrity of the information created through this chain is a core design principle and is a fundamental requirement to fulfil the true potential of the IoT.
