AP2146/AP2156 0.5A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2146 and AP2156 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 EN1 1 8 OUT1 available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise 2 7 FLG1 IN time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting 3 6 FLG2 GND and does not require any external components. 4 5 EN2 OUT2 All devices are available in SO-8 and MSOP-8EP packages.
