AP22811 SINGLE CHANNEL POWER DISTRIBUTION LOAD SWITCH Description Pin Assignments The AP22811 is a single channel current-limited integrated high-side (Top View) power switch 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. OUT 1 5 IN The device has fast short-circuit response time for improved overall GND 2 system robustness, and has an integrated output discharge function to ensure completely controlled discharging of the output voltage FLG 3 4 EN/EN 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, over-current, over-temperature SOT25 and short-circuit protection, as well as controlled rise time and (Top View) under-voltage lockout functionality. A 6ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does 1 8 OUT GND not require any external components. 7 IN 2 OUT The AP22811 is available in a standard Green SOT25 and MSOP-8 6 OUT IN 3 packages with RoHS compliant. 4 5 EN/EN FLG Features MSOP-8 Input Voltage Range: 2.7V to 5.5V 50m On-resistance Applications Built-in Soft-start with 0.6ms Typical Rise Time Integrated Load Switches in Ultrabook PCs Fault Report (FLG) with Blanking Time (6ms Typ.)
