AP2301/AP2311 2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2301 and AP2311 are single channel current-limited (Top View) ( Top View ) integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices GND 1 8 NC complies with USB standards and is available with both polarities of IN 2 7 OUT Enable input. 3 6 IN OUT The devices have fast short-circuit response time for improved overall EN 4 5 FLG system robustness, and have integrated output discharge function to ensure completely controlled discharging of the output voltage SO-8 SO-8 capacitor. They provide a complete protection solution for applications (Top View) 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. MSOP-8 /MSOP-8EP All devices are available in SO-8, MSOP-8, MSOP-8EP, U-DFN3030- Note: latter with exposed pad (dotted line) 8 (Type E) and U-DFN2020-6 packages.
