A4776A Datasheet | AiT Semiconductor

DESCRIPTION FEATURES The A4776A is available in SOT25 Package - The A4776A is a USB output protection chip with - adjustable current limit threshold for 5V applications. The device integrates over current protection, short - protection, over temperature protection, under voltage lock-out protection functions, etc. It can limit - output current when short event happens or heavy - capacitive load is applied to the USB output, so as to protect the supply voltage source from collapsing. Low on resistance: 70mΩ Current-limit threshold adjustable by external resistor Current limit accuracy over full operating conditions：±15% Output short fast response and protection No parasitic substrate diode, and reverse current blocking when switch is off.
