AP22804 / AP22814 SINGLE CHANNEL POWER DISTRIBUTION LOAD SWITCH Description Pin Assignments The AP22804/AP22814 is a single channel current-limited integrated high-side power switch optimized for Universal Serial Bus (USB) and (Top View) other hot-swap applications. The family of devices complies with USB standards and is available with both polarities of Enable input. 1 8 NC GND 7 IN 2 OUT The device has fast short-circuit response time for improved overall 6 OUT IN 3 system robustness, and has an integrated output discharge function 4 5 EN FLG to ensure completely controlled discharging of the output voltage capacitor. They provide a complete protection solution for applications MSOP-8 subject to heavy capacitive loads and the prospect of short circuit, and offer reverse current blocking, over-current, over-temperature (Top View) and short-circuit protection, as well as controlled rise time and under-voltage lockout functionality. A 6ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. The AP22804/AP22814 is available in a standard Green SOT25, MSOP-8 and U-DFN2020-6 packages with exposed PAD for improve thermal performance and is RoHS compliant.
