The AP2301A and AP2311A are single channel 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 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 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, MSOP 8 and U-DFN2020-6 packages.
