Description
The AP2301 and AP2311 are single channel current-limited integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devicescomplies with USB standards and is 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 applications 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 undervoltage lockout functionality. A 7ms deglitch capability on the opendrain Flag output prevents false over-current reporting and does notrequire any external components.
All devices are available in SO-8, MSOP-8, MSOP-8EP, U-DFN3030-8 (Type E) and U-DFN2020-6 packages.
