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.

Caution: Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.

Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices.
