A4776 Datasheet | AiT Semiconductor

DESCRIPTION FEATURES The A4776 is Adjustable USB Load Current Switch - 2.5 to 5.5V input voltage range Current Limited designed for high-side load switching - Controlled turn-on applications. The internal current-limiting circuit - 0.15-1.3A adjustable current limit protects the input supply against large output short - ±6% current limit accuracy circuit current which may cause the supply to fall out - 0.25ohm on resistance of regulation. - Fast current limit response time The current limit threshold is programmed with an - Logic Control Shutdown (IQ<1u A) external resistor from ISET Pin to ground. The - Thermal shutdown and UVLO quiescent supply current is typically 150μA, making - Reverse current blocking the device ideal for portable battery-operated - Available in SOT-25 Package equipment. In shutdown mode, the supply current decreases to less than 0.1μA. APPLICATION Additional features include thermal shutdown and constant current output characteristics if current - Portable Devices exceed its current limit. - MID, MP4… - Set top boxes The A4776 is available in SOT-25 package. - Notebook and PC mother board - USB supplied Devices ORDERING INFORMATION TYPICAL APPLICATION Package Type Part Number SOT-25 A4776E5R E5 SPQ: 3,000pcs/Reel A4776E5VR Note V: Halogen free Package R: Tape & Reel Ai T provides all Ro HS products REV1.1 - JAN 2014 RELEASED, JAN 2019 UPDATED - -1- Ai T Semiconductor...
