The TMI6262AL is a cost-effective, low voltage, single PMOSFET load switch, optimized for self-powered and buspowered Universal Serial Bus (USB) applications. This  switch operates with inputs ranging from 2.5V to 5.5V,  making it ideal for both 3V and 5V systems. The switch's  low RDS(ON), 60mΩ, meets USB voltage drop requirements.  A built-in P-channel MOSFET with true shutdown function  to eliminate any reversed current flow across the switch  when it is powered off. When the output voltage is higher  than input voltage, the power switch is turned off by  internal output reverse-voltage comparator. The TMI6262AL offers a programmable current limit  threshold between 400mA to 2.4A via an external resistor.
