AP2161/ AP2171 1A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2161 and AP2171 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 1 8 GND NC available with both polarities of Enable input. They offer current and 2 7 OUT IN thermal limiting and short-circuit protection as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability IN 3 6 OUT on the open-drain Flag output prevents false overcurrent reporting and does not require any external components.
