Abstract
A power management integrated circuit for monitoring a parameter of a power system includes: an analog front end operative to receive and at least one of amplify, attenuate and filter analog signals representative of at least one of voltage and current in a power system to produce modified analog signals; an analog to digital converter operative to produce digital signals; the logic coupled with the analog to digital converter operative to receive the digital signals and produce a power parameter and the logic includes a processor core; a random access memory coupled with the logic operative to store the power parameter and the logic is operative to implement a setpoint to detect when the power parameter is outside a determined range; and a digital output coupled with the first logic and the digital output is useable to control a switching circuit outside the power management integrated circuit.
