Driver Monitoring Systems
Driver Monitoring Systems Content
Driver monitoring systems are one of the latest developments in automotive safety technology. As part of a holistic human-machine interface (HMI), driver monitoring systems track vital sign parameters and driver attentiveness, so that in the event that the driver is unable to operate the vehicle, assistance can be provided. Of course, advanced new features add design complexity and additional considerations for the engineer. Because safety is always the top priority, these components must meet strict EMI and temperature requirements so that consumers and manufacturers can feel confident in improved comfort and convenience while minimizing driver distraction.
Our top-performing catalog of automotive-grade solutions includes power modules, PMICs, step-down converters, and linear regulators. These components pack top-tier flexibility and efficiency into a small package size, saving cost and board space to improve time-to-market.
MPS’s reliable, cost-effective power management solutions provide everything you need to power the next generation of driver monitoring systems.

DESIGNING THE FEEDBACK VOLTAGE RESISTOR DIVIDER IN A DC/DC CONVERTER
The specifications of the feedback (FB) voltage resistor divider in DC-DC converters often poses various design challenges, such as determining the required resistance or adjusting parameters (e.g. output voltage, upper divider resistance or lower divider resistance). Figure 1 shows the various magnitude combinations for the FB upper and lower divider resistances. This article examines the ...
DESIGNING A POWER TREE FOR AN AUTOMOTIVE SOC
Advanced driver assistance systems (ADAS) and infotainment system-on-chips (SoCs) are offering increasingly higher computing power, which in turn results in higher power demands. An SoC can require more than 10 different power rails, with currents ranging from hundreds of amperes (A) to a few mA. Crafting an optimal power tree for these applications is not a trivial task.

RECOGNITION AND ELIMINATION OF SUBHARMONIC OSCILLATIONS
DC/DC instability occurs due to a variety of factors, such as improper compensation parameters or insufficient layout. This article will discuss subharmonic oscillations, a form of instability that can be generated when current mode switching regulators have a continuous inductor current and a duty cycle exceeding 50%. These oscillations then create unstable power supplies. To learn about subharm...
EVALUATING THE TRANSIENT PERFORMANCE OF BUCK REGULATORS WITH AN INTEGRATED COMPENSATION NETWORK
Designing the compensation network for buck regulators can be tedious and may require several iterations to optimize the solution. Having an optimized control loop, which can enable fast transient response while maintaining proper stability, has become a major challenge with the emergence of new applications such as ADAS and fast transient response requirements. To address these issues, buck regul...
DOMAIN CONTROL MODULE - AUTOMOTIVE POWER STAGE FOR ADAS APPLICATIONS
Advanced driver assistance systems (ADAS) have experienced an astonishing evolution over the last few decades, and todays cars incorporate a large number of sensors and cameras that monitor every part of the vehicle, as well as its surroundings. As a consequence, the power requirements of these systems has increased, bringing new challenges to the power supply design. This reference design serves ...
USING EXTERNAL KNOBS TO IMPROVE TRANSIENT PERFORMANCE OF BUCK REGULATORS WITH AN INTEGRATED COMPENSATION NETWORK
The high power density requirement and board-level space constraints in modern applications — such as lighting, ADAS, and USB — call for higher integration in buck regulators. There is a trend to integrate MOSFETs and compensation networks inside the chip. This integration of the compensation network’s passive components saves cost, board space, and design iterations. However, it...

E-TRACKER REFERENCE DESIGN
Tracking the location of different types of vehicles is an increasingly popular application for multiple purposes, such as control of transport trucks or anti-theft security. However, this presents two challenges in electronic design. First, the system must be able to track a vehicle’s location when the car battery is turned off. Second, the GSM modules that establish communication with the ...
EASY, COST-EFFECTIVE PRE-BOOSTER FOR AUTOMOTIVE COLD CRANK CONDITIONS
Start-stop functionality is expected to be featured in more and more new car models from any manufacturer. However, this presents a challenge in automotive electronics design as starting the motor in cold weather can make the battery’s voltage drop as low as 3V. This is called a “cold crank.” The power stage for most 12V automotive systems consists of a single buck converter tha...
