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 f
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-
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 over
current reporting and does
not require any external components. AP2401A and AP2411A
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.
