Datasheet Summary
Adjustable USB Load Current Switch
DESCRIPTION
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. The quiescent supply current is typically 150μA, making the device ideal for portable batteryoperated equipment. In shutdown mode, the supply current decreases to less than 0.1μA.
Additional Features include thermal shutdown and constant current output characteristics if...
