Description

The AP2142A and AP2152A are dual 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 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 application 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-EP

and

DFN3030E-8 packages.
