Description
Item Description:
The AP2162A and AP2172A are dual channel current-limit 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, overcurrent, overtemperature and short-circuit protections, as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain flag output prevents false overcurrent reporting and does not require any external components. Both devices are available in SO-8, MSOP-8EP and U-DFN3030-8 (Type E) packages.
