AP2142/ AP2152 0.5A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2142 and AP2152 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 GND 1 8 FLG1 available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise 2 7 OUT1 IN time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting 3 6 EN1 OUT2 and does not require any external components. EN2 4 5 FLG2 All devices are available in SO-8 and MSOP-8EP packages.
