AP2141D/ AP2151D 0.5 SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH OUTPUT DISCHARGE Description Pin Assignments The AP2141D and AP2151D are integrated high-side power switches (((( TTTToooopppp VVVViiiieeeewwww )))) 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 over-current reporting and 3 6 IN OUT does not require any external components. All devices are available in SOT25, SO-8, MSOP-8EP, and EN 4 5 FLG U-DFN2018-6 packages.
