TMI6263BH数据手册Tollsemi中文资料规格书

描述 Description

The TMI6263 is a cost-effective, single P-MOSFET load switch with ultra-low RDS(ON), optimized for self-powered 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. TheTMI6263BH offers a programmable current limit threshold between 200mA to 2.4A via an external resistor.
