描述 Description

The AP2141D and AP2151D are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devicescomplies 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.
