AP2162A/AP2172A
1A DUAL CHANNEL CURRENT-LIMITED
POWER SWITCH WITH OUTPUT DISCHARGE
Description
Pin Assignments
The DIODES™ AP2162A and DIODES™ AP2172A are dual 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 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 function to
ensure completely controlled discharging of the output voltage
capacitor. They provide a complete protection solution for application
subject to heavy capacitive loads and the prospect of short circuit,
and offer reverse current blocking, over-current, over-temperature
and short-circuit protections, as well as controlled rise time and
under-voltage lockout functionality. A 7ms deglitch capability on the
open-drain flag output prevents false over-current reporting and does
not require any external components.
