Diodes Incorporated AP2191SG-13

Description
The AP2181 and AP2191 are integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. They comply with USB 2.0 and are available with both polarities of Enable input. These devices offer current and thermal limiting, short circuit protection, controlled rise time, and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting without requiring external components.
