AP22804 / AP22814

SINGLE CHANNEL POWER DISTRIBUTION LOAD SWITCH

Description

The AP22804/AP22814 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 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.
