Green
2.0A SINGLE CHANNEL CURRENT-LIMITED
POWER SWITCH WITH LATCH-OFF
Description
Pin Assignments
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.
