AP22804 / AP22814
SINGLE CHANNEL POWER DISTRIBUTION LOAD SWITCH
Description Pin Assignments
The AP22804/AP22814 is a single channel current-limited integrated
high-side power switch optimized for Universal Serial Bus (USB) and (Top View)
other hot-swap applications. The family of devices complies with USB
standards and is available with both polarities of Enable input.

to ensure completely controlled discharging of the output voltage
capacitor. They provide a complete protection solution for applications
MSOP-8
subject to heavy capacitive loads and the prospect of short circuit,
and offer reverse current blocking, over-current, over-temperature
(Top View)
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 AP22804/AP22814 is available in a standard Green SOT25,
MSOP-8 and U-DFN2020-6 packages with exposed PAD for improve
thermal performance and is RoHS compliant.
