1.5A High-side Power Distribution Switch with Enable and Flag AP2815

Advance Datasheet

General Description

The AP2815 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 R to meet the USB voltage drop requirements. The IC integrates 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 remains off unless there is a valid input voltage present. A FLAG output is available to indicate fault conditions to the local USB controller.

The AP2815 is available in standard packages of SOIC-8 and MSOP-8.
