AP2501/AP2511

2.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH

Description

The AP2501 and AP2511 are single channel current-limited

integrated high-side power switches optimized for Universal Serial

Bus (USB) and other hot-swap applications. The family of devices

complies with USB standards and is available with both polarities of

Enable input.

The devices have fast short-circuit response time for improved

overall system robustness, and have integrated output discharge

function to ensure completely controlled discharging of the output

voltage capacitor. They provide a complete protection solution for

applications subject to heavy capacitive loads and the prospect of

short circuit, and offer reverse current blocking, over-current, over-

temperature 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 SO-8, MSOP-8, MSOP-8EP and

U-DFN3030-8 Type E packages.
