AP22804, AP22811, and AP22814 Load Switches

Diodes' AP22804, AP22811, and AP22814 are single-channel, current-limited, integrated high-side power switches optimized for universal serial bus (USB) and other hot-swap applications. The family of devices complies with USB standards and is available with both polarities of enable input. The devices have fast short-circuit response time for improved overall system robustness, and have 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. They offer reverse current blocking, over current, over temperature, and short-circuit protection, as well as controlled rise time and under voltage lockout functionality. A 6 ms deglitch capability on the open-drain flag output prevents false over current reporting and does not require any external components. The AP22804, AP22811, and AP22814 are available in a standard green SOT25 and MSOP-8 packages with RoHS compliance.
