AP2401A/AP2411A

2.0A SINGLE CHANNEL CURRENT-LIMITED

POWER SWITCH WITH LATCH-OFF

Description

The AP2401A and AP2411A 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, overcurrent, over-temperature and

short-circuit

protection,

as

well

as

controlled

rise time

and

undervoltage lockout functionality. A 7ms deglitch capability on the

open-drain Flag output prevents false overcurrent reporting and does

not require any external components. AP2401A and AP2411A will be

latched off after a 7ms deglitch.

All

devices

are

available

in

SO-8,

MSOP-8,

MSOP-8EP,

U-DFN3030-8 and U-DFN2020-6 packages.
