AP2822GKETR-G1

The AP2822 is an integrated high - side power switch that consists of N - Channel MOSFET, charge pump, over current & temperature and other related protection circuits. The switch's low RDS(ON), 85mΩ is designed to meet USB voltage drop requirements. The IC includes soft - start to limit inrush current, over - current protection, load short protection with fold - back, and thermal shutdown to avoid switch failure during hot plug - in. Under voltage lockout (UVLO) function is used to ensure the device remain off unless there is a valid input voltage present. A FLAG output is available to indicate fault conditions to the local USB controller. The AP2822 is available in the standard package of SOT - 23 - 5.
