AP2181A/AP2191A

1.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH

Description

Pin Assignments

The AP2181A and AP2191A are integrated high-side power switches

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

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

available with both polarities of Enable input. The AP2181A and

AP2191A offer current and thermal limiting and short circuit protection

as well as controlled rise time and undervoltage lockout functionality.

A 7ms deglitch capability on the open-drain Flag output prevents false

over-current reporting and does not require any external components.
