描述 Description

The TMI6260X is a cost-effective, low voltage, single P-MOSFET load switch, optimized for self-powered and bus-powered 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 TMI6260X offers a programmable current limit threshold via an external resistor on ILIM pin to GND. nFLG is an open-drain output report over-current or over temperature event. In addition, nFLG also has typical 2.5ms deglitch timeout period and reports output reverse-voltage condition.
