BL2556 DESCRIPTION 1A USB Load Current Switch with 5V Output Voltage Limit FEATURES The BL2556 is 1A USB Load Current Switch with output voltage limit at 5V, 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 output voltage limiting function protects the output over voltage when BL2556’s Vin sees voltage surge. The current limit is fixed around 1.4A which allow 1A USB application. The quiescent supply current is typically 15μA, making the device ideal for portable battery-operated equipment. In shutdown mode, the supply current decreases to less than 0.1μA.
