Description: Single Channel USB Power Distribution Switch

Features

* +3.0V to +5.5V Input Voltage Range
* 500mA Continuous Load Current per Channel
* 2.6V Undervoltage Lockout
* 1.25A Short Circuit Current Limit
* 100mΩ Maximum On-Resistance
* 75μA On-State Supply Current
* 1μA Shutdown Current
* Output can be Forced Higher than Inpu

Applications

* The high-side switches are MOSFETs with 70mΩ RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or under voltage lockout. Output current is typically limited to 0.85A
