GENERAL DEscriptION
The SGM2554 is a single channel power distribution switch. The switch operates from a wide range of 2.2V to 5.5V supply voltage, and is controlled by the EN pin. It can be used in USB power distribution applications.
A 95mΩ 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 of 1.85A and thermal shutdown. The internal reverse-voltage function will protect devices on the input side of the switch.
The SGM2554 is available in a Green SOT-23-5 package and is rated over the -40℃ to +85℃ temperature range.
