摘要
Aspects of the disclosure are directed to a System on a Chip (SOC). In accordance with one aspect, a method for implementing back power protection (BPP) in a SOC includes transmitting a first back power protection (BPP) supply output from a first power management integrated circuit (PMIC) to a logical OR function; transmitting a second back power protection (BPP) supply output from a second power management integrated circuit (PMIC) to the logical OR function; using the logical OR function to generate a composite BPP power based on the first BPP supply output and the second BPP supply output; and inputting the composite BPP power to a baseband processor (BP), wherein the baseband processor (BP) is coupled to the second PMIC.
