SINGLE CHANNEL POWER DISTRIBUTION LOAD SWITCH

Description

The AP22802 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 AP22802 is available in a standard Green SOT25 and RoHS

compliant.
