Green AP2401/AP2411 2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH LATCH-OFF Description Pin Assignments The AP2401 and AP2411 are single channel current-limited (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. OUT IN 3 6 The devices have fast short-circuit response time for improved overall system robustness, and have integrated output discharge function to EN 4 5 FLG ensure completely controlled discharging of the output voltage 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 GND 1 8 NC and short-circuit protection, as well as controlled rise time and IN 2 7 OUT under-voltage lockout functionality. A 7ms deglitch capability on the IN 3 6 OUT open-drain Flag output prevents false over-current reporting and does 4 5 FLG EN not require any external components. AP2401 and AP2411 will be latched off after 7ms deglitch. MSOP-8/MSOP-8EP Note: Latter with exposed pad All devices are available in SO-8, MSOP-8, MSOP-8EP, (dotted line) U-DFN3030-8 and U-DFN2020-6 packages.
