BL2554 Adjustable USB Load Current Switch DESCRIPTION FEATURES 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 current exceed its current limit. The BL2554 is available in SOT23-5 and SOT23-6 packages. TYPICAL APPLICATION 2.5 to 5.5V input voltage range Controlled turn-on 0.15-1.3A adjustable current limit +/-6% current limit accuracy 0.25ohm on resistance Fast current limit response time Logic Control Shutdown (IQ<1uA) Thermal shutdown and UVLO Reverse current blocking SOT23-5 and SOT23-6 packages APPLICATIONS      Portable Devices MID, MP4… Set top boxes Notebook and PC mother board USB supplied Devices PIN OUT & MARKING BL2554 ORDERING INFORMATION Part No. Package Tape&Reel BL2554CB5TR SOT23-5 3000/Reel BL2554CB6TR SOT23-6 3000/Reel www.belling.com.cn SOT23-5 SOT23-6 Note: YW means the year and week parts being manufactured, subjected to change.
