Description

The AP2821 is an integrated high-side power switch that consists of TTL compatible enables input, a charge pump, and n-channel MOSFET. The switchandrsquo;s low RDS(ON), 120mandOmega;, meets USB voltage drop requirements. It includes soft-start to limit inrush current, overcurrent protection with fold-back, and thermal shutdown to avoid switch failure during hot plug-in. Undervoltage lockout (UVLO) function is used to ensure the device remains off unless there is a valid input voltage present. And no reverse current when power off, with shutdown pull-low resistor to discharge the output capacitor when EN is disabled.
