AP2161/ AP2171 1A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description The AP2161 and AP2171 are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and is available with both polarities of Enable input. They offer current and thermal limiting and short-circuit protection as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false overcurrent reporting and does not require any external components. All devices are available in SO-8, MSOP-8EP, SOT25, and U-DFN2018-6 packages Features  Single USB Port Power Switches  Overcurrent and Thermal Protection  1.
