AP2142A/ AP2152A
0.5A DUAL CHANNEL CURRENT-LIMITED
POWER SWITCH WITH OUTPUT DISCHARGE
Description
The AP2142A and AP2152A 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.

5. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
6. The discharge function is active when the device is disabled (when enable is de-asserted or during power-up / power-down when V

discharge function offers a resistive discharge path for the external storage capacitor for limited time.
7. Test condition for SO-8: Device mounted on FR-4 substrate PCB with minimum recommended pad layout.
