Green AP2145/ AP2155 0.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH Description Pin Assignments The AP2145 and AP2155 are integrated high-side power switches SO-8 optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and EN 1 8 OUT available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise FLG 2 7 IN time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting 3 6 GND OUT and does not require any external components. 4 5 NC NC All devices are available in SO-8 and MSOP-8EP packages.

These are stress ratings only functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices Note: 4.
