Green AP2181D/AP2191D 1.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE Description Pin Assignments The AP2181D and AP2191D are integrated high-side power switches ( Top View ) optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and is GND 1 8 NC available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise 2 7 OUT IN time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain flag output prevents false overcurrent reporting and 3 6 IN OUT does not require any external components. EN 4 5 FLG All devices are available in SO-8, MSOP-8, MSOP-8EP, SOT25, and SO-8 U-DFN2018-6 packages.
