The TMI6263 is a cost-effective, single P-MOSFET  load switch with ultra-low RDS(ON), optimized for selfpowered and bus-powered Universal Serial Bus (USB)  applications. Input voltage from 2.5V to 5.5V, making it  ideal for both 3V and 5V systems. A built-in P-channel  MOSFET with true shutdown function to eliminate any  reversed current flow across the switch. When output  voltage is higher than input voltage, power switch is  turned off. The TMI6263BH offers a programmable current limit  threshold between 200mA to 2.4A via an external  resistor.
