0.5A to 2.0A High-side Power Distribution Switches AP2822

Preliminary Datasheet

General Description

The AP2822 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 USB voltage drop requirements. The IC
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 AP2822 is available in the standard package of
SOT-23-5.
