Original Abstract Submitted
Techniques and apparatus for power supply monitoring in in-vehicle systems, such as advanced driver assistance systems (ADASs), in-vehicle infotainment (IVI) systems, and/or automated driving (AD) systems. One example method of power supply monitoring generally includes regulating power to a main domain of a system on a chip (SoC) using at least one main domain (MD) power management integrated circuit (PMIC); regulating power to a safety domain of the SoC using at least one safety domain (SD) PMIC; powering the at least one SD PMIC using a SD PMIC power supply rail; and monitoring the SD PMIC power supply rail using the at least one MD PMIC. For certain aspects, the method further includes powering the at least one MD PMIC using a MD PMIC power supply rail and monitoring the MD PMIC power supply rail using the at least one SD PMIC.
