Abstract

See full text

A power management integrated circuit (PMIC) chip provides power loss protection to an application device. The PMIC chip has several storage pins that each receives a set of storage capacitors that are charged using power from a power source during normal operation. An application device receives power from the power source during normal operation and receives power from an operational set of storage capacitors during power loss. A failing set of storage capacitors is disconnected from an operational set of storage capacitors and from the PMIC chip. The operational set of storage capacitors remains connected to the PMIC chip to provide power loss protection.
