AP2181A中文资料1.5A Single Channel Current-Limited Power Switch数据手册Diodes规格书

描述 Description

The AP2181A and AP2191A are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. This family of devices complies with USB 2.0 and is available with both polarities of Enable input. The AP2181A and AP2191A offer current and thermal limiting and short circuit protection as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components.

\t 

\tAll devices are available in SO-8, MSOP-8EP, SOT25 and U-DFN2018-6 packages.
