AP2145/AP2155

0.5A SINGLE CHANNEL CURRENT-LIMITED POWER

SWITCH WITH OUTPUT DISCHARGE

Description

Pin Assignments

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 components.
