SGM2578数据手册SGMICRO中文资料规格书

描述 Description

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℃ to +85℃.
