1.0A DUAL CHANNEL CURRENT-LIMITED POWER
SWITCH WITH OUTPUT DISCHARGE
Description
Pin Assignments
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-8-EP and
DFN3030E-8 packages.
