The AP22811 is a single channel current-limit integrated high-side power switch optimized for Universal Serial Bus (USB) and other hotswap applications. The family of devices complies with USB standards and is available with both polarities of Enable input.
The device has fast short-circuit response time for improved overall system robustness, and has an integrated output discharge function to ensure completely controlled discharging of the output voltage capacitor. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuit, and offer reverse current blocking, overcurrent, overtemperature and shortcircuit protection, as well as controlled rise time and undervoltage lockout functionality. A 6ms deglitch capability on the open-drain Flag output prevents false overcurrent reporting and does not require any external components.
The AP22811 is available in standard Green SOT25 and MSOP-8 packages with RoHS compliance.
