GENERAL DESCRIPTION
The SGM2580 is a single channel power distribution
switch. The switch operates from a wide range of 2.5V
to 5.5V supply voltage, and is controlled by the EN pin.
It can be used in USB power distribution applications.
A 100mΩ 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. Thermal shutdown shuts off the output
MOSFET and asserts the nFAULT output if the die
temperature exceeds +150℃, and the output MOSFET
remains off until the die temperature drops to +130℃.
The nFAULT pin asserts low during fault conditions
after a 13ms blanking time to prevent false reporting.
SGM2580 is available in a Green SOT-23-5 package. It
is rated over the -40℃ to +85℃ temperature range.
