AP2151A数据手册集成电路（IC）的配电开关负载驱动器规格书PDF

描述 Description

The AP2141A and AP2151A are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB 2.0 and is available with both polarities of Enable input. They offer current and thermal limiting and short circuit protection as well as controlled rise time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. All devices are available in SO-8, MSOP-8EP, SOT25, and U-DFN2018-6 packages.
