BL2554 Overview
The BL2554 is Adjustable USB Load Current Switch Current Limited designed for high-side load switching applications. The internal currentlimiting circuit protects the input supply against large output short circuit current which may cause the supply to fall out of regulation. The current limit threshold is programmed with an external resistor from ISET Pin to ground.
