PART OBSOLETE – USE AP22811AM8-13, AP22811BM8-13 AP2820 2.0A HIGH-SIDE POWER DISTRIBUTION SWITCH WITH ENABLE AND FLAG OBSOLETE – PART DISCONTINUED Description Pin Assignments (Top View) The AP2820 is an integrated high-side power switch that consists of TTL compatible 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. Undervoltage lockout (UVLO) function ensures the device remains off unless there is a valid input voltage present. A flag output is available to indicate fault conditions to the local USB controller.
