Abstract
A power management system permits a small microcontroller subsystem or low power domain to continuously operate while a main subsystem domain is cycling from power on to off. The power management system supports asynchronous domains with common shared peripherals. The asynchronous domains operate as a single entity while in a full power mode with the peripheral and system resources being shared. The system can be used in automotive systems where most of the system is power-gated leaving just a power regulator controller, some counters and an input/output segment alive for wakeup purposes.
