AP2141/ AP2151 0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2141 and AP2151 are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap ( Top View ) applications. This family of devices complies with USB 2.0 and is available with both polarities of Enable input. They offer current and GND 1 8 NC thermal limiting and short circuit protection as well as controlled rise IN 2 7 OUT time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting 3 6 IN OUT and does not require any external components.
