AP2820 Description
The AP2820 is an integrated high-side power switch that consists of TTL patible enables input, a charge pump, and N-Channel MOSFET. The switch’s low RDS (ON), 70mΩ, meets USB voltage drop requirements. The device includes soft-start to limit inrush current, overcurrent protection with foldback, and thermal shutdown to avoid switch failure during hot plug-in.
