SWITCH 70mΩ 5V USB HIGH SIDE CURRENT LIMIT LOAD SWITCH
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.
