0.5A SINGLE CHANNEL CURRENT-LIMITED POWER

SWITCH

Description

Features

The AP2145 and AP2155 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

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
