General Description

The AP2810 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 RDS (ON), 60m

Ω, design

easily to meet USB voltage drop requirements. It

includes 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 remain off unless there is a

valid input voltage present. A Flag output is available

to indicate fault conditions to the local USB

controller.

The AP2810 is available in standard packages of

SOIC-8 and MSOP-8.
