The SGM2558 is a dual-channel power distribution switch. The switch operates from a wide range of 2.7V to 5.5V supply voltage, and is controlled by the ENx pin. It can be used in USB power distribution applications.
A 90mΩ 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. Fault conditions are indicated by the FAULTx pin. Transient faults are filtered internally.
The SGM2558 is available in Green SOIC-8 and TDFN-3×3-8L packages. It is rated over the -40℃ to +85℃ temperature range.
