Power management integrated circuits (PMICs) are specialized integrated circuits (ICs) designed to provide control and management of various circuit power rails and or power management functions required for a system or gateway application. PMICs are commonly used in modem, router and other gateway applications, as well as in a variety of consumer electronics devices, medical devices, and industrial controls. One of the key elements of PMICs is known as a \'supervisor module\' which is responsible for monitoring and preventing overcurrent events, resetting the system when faults occur, and providing accurate real-time status information on system status and power conditions.
