Abstract
A reverse current protection (RCP) circuit is provided that includes an RCP switch coupled between a power supply rail and a buffer power supply node. A control circuit powered by a buffer supply voltage on the buffer power supply node controls the RCP switch to open in response to a discharge of a power supply voltage carried on the power supply rail.
