The SGM2551A and SGM2551C are single channel power distribution switches. The switch operates from a wide range of 2.5V to 5.5V supply voltage, and is controlled by the EN pin.


A 90mΩ low RON N-MOSFET is integrated. It is capable of supplying up to 1.5A continuous current. 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, adjustable current limit and thermal shutdown. This device provides a programmable current limit threshold between 100mA and 1.7A through the RILIM. The internal reverse-voltage function will protect devices on the input side of the switch. The SGM2551C has quick output discharge function in disable status.


SGM2551A and SGM2551C are available in the Green TDFN-2×2-6L and SOT-23-5 packages. They are rated over the -40℃ to +85℃ temperature range.
