AP2501/AP2511 Green 2.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2501 and AP2511 are single channel current-limited (Top View) (Top View) integrated high-side power switches optimized for Universal Serial ( Top View ) Bus (USB) and other hot-swap applications. The family of devices 1 8 GND NC complies with USB standards and is available with both polarities of Enable input. IN 2 7 OUT IN 3 6 OUT The devices have fast short-circuit response time for improved overall system robustness, and have integrated output discharge EN 4 5 FLG function to ensure completely controlled discharging of the output U-DFN3030-8 (Type E) SO-8 SO-8 voltage capacitor. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of (Top View) (Top View) 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. MSOP-8 /MSOP-8EP All devices are available in SO-8, MSOP-8, MSOP-8EP, U-DFN2020-6 Note: latter with exposed pad U-DFN3030-8 (Type E) and U-DFN2020-6 packages.
