AP2301/AP2311

2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH

Description

The AP2301 and AP2311 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, U-DFN3030-

8 and U-DFN2020-6 packages.
