GENERAL DEscriptION
The SGM2576 and SGM2576B are single channel power distribution switches. The switches operate from a wide range of 2.5V to 5.5V supply voltage, and are controlled by the EN pin.
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, programmable current limit and thermal shutdown. This device provides a programmable current limit threshold between 100mA and 2.5A through the RILIM. Thermal shutdown shuts off the output MOSFET if the die temperature exceeds +150℃, and the output MOSFET remains off until the die temperature drops to +130℃.
SGM2576 and SGM2576B are available in a Green SOT-23-5 package. They are rated over the -40℃ to +85℃ temperature range.
