2.1 ASIL-D Requirements

ASLIL-D functional safety has several voltage monitoring and CPU health requirements that are beyond the scope of this application report. There are various methods to meet these requirements. One approach is to use a power management IC that not only delivers power to the MCU, but also integrates various voltage monitoring and watchdog features needed to meet ASIL-D requirements. The PMIC selected to meet the ASIL-D requirements should meet all the following criteria.
