AP22811
SINGLE CHANNEL POWER DISTRIBUTION LOAD SWITCH
Description
The AP22811 is a single channel current-limited integrated high-side
power switch 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 device has fast short-circuit response time for improved overall
system robustness, and has an 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 6ms deglitch capability on the
open-drain Flag output prevents false over-current reporting and does
not require any external components.
The AP22811 is available in a standard Green SOT25 and MSOP-8
packages with RoHS compliant.
