AP2822
0.5A to 2.0A HIGH-SIDE POWER DISTRIBUTION SWITCHES
Description
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), 85mis 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.
