AP2401/AP2411

2.0A SINGLE CHANNEL CURRENT-LIMITED

POWER SWITCH WITH LATCH-OFF

Description

The AP2401 and AP2411 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. AP2401 and AP2411 will be
latched off after 7ms deglitch.

All devices are available in SO-8, MSOP-8, MSOP-8EP,
U-DFN3030-8 and U-DFN2020-6 packages.
