6V Power Distribution Switches

A power distribution switch is an electronic switch specifically designed to control and protect the power outputs of multiple loads. It is commonly used in USB power switches, power rails in system modules, and power distribution systems requiring overcurrent protection. It typically incorporates a MOSFET with low on-resistance to reduce voltage drop and heat generation. Its functions include: allowing the system to control the power rails on and off using logic signals; automatically limiting current or shutting down the output to prevent power supply damage when the load is short-circuited or draws excessive current; automatically cutting off power when the chip temperature is too high to prevent overheating damage; and preventing load voltage from flowing back into the main power supply.
