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

Apr. 2012 Rev 1. 7 BCD Semiconductor Manufacturing Limited

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

DS(ON)

, 60mΩ, is designed

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.
