AP2161D/AP2171D

1A SINGLE CHANNEL CURRENT-LIMITED

POWER SWITCH WITH OUTPUT DISCHARGE

Description

The AP2161D and AP2171D are integrated high-side power switches

optimized for Universal Serial Bus (USB) and other hot-swap

applications. The family of devices complies with USB 2.0 and is

available with both polarities of Enable input. They offer current and

thermal limiting and short circuit protection as well as controlled rise

time and under-voltage lockout functionality. A 7ms deglitch capability

on the open-drain Flag output prevents false over-current reporting

and does not require any external components.

All devices are available in SOT25, SO-8, MSOP-8, MSOP-8EP, and

U-DFN2018-6 packages.
