SGM2578 Ultra Small, Low Input Voltage, Low RON Load Switch
■The SGM2578 is a single channel power distribution switch. The switch operates from a wide range of 1V to 5V supply voltage, and is controlled by the EN pin. It can be used in USB power distribution applications.
■A 54mΩ low RON N-MOSFET is integrated. The small size and quiescent current make the device very suitable for space limited, battery-powered applications.
■A number of protection features are provided in the device including soft-start, current limit and thermal shutdown. The internal reverse-voltage function will protect devices on the input side of the switch. The SGM2578 has automatic discharge function to quickly discharge VOUT in the disabled status.
■The SGM2578 is available in a Green WLCSP-0.9×0.9-4B package and operates over a temperature range of -40°C to +85°C.
