AP2162A/ AP2172A
1A DUAL CHANNEL CURRENT-LIMITED
POWER SWITCH WITH OUTPUT DISCHARGE
Description
The AP2162A and 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 protection, 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.
All devices are available in SO-8, MSOP-8EP and U-DFN3030-8
packages.
