==POWER MANAGEMENT INTEGRATED CIRCUIT (PMIC) POWER SUPPLY MONITORING WITHOUT EXTERNAL MONITORING CIRCUITRY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18457066 titled 'POWER MANAGEMENT INTEGRATED CIRCUIT (PMIC) POWER SUPPLY MONITORING WITHOUT EXTERNAL MONITORING CIRCUITRY

==Simplified Explanation==

The patent application describes techniques and apparatus for monitoring power supply in in-vehicle systems, such as ADASs, IVI systems, and/or AD systems.

* Regulating power to the main domain of a System on a Chip (SoC) using at least one Main Domain (MD) Power Management Integrated Circuit (PMIC)
* Regulating power to the safety domain of the SoC using at least one Safety Domain (SD) PMIC
* Powering the SD PMIC using a SD PMIC power supply rail
* Monitoring the SD PMIC power supply rail using the at least one MD PMIC
* Powering the MD PMIC using a MD PMIC power supply rail
* Monitoring the MD PMIC power supply rail using the at least one SD PMIC

==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.
