    SGM2576/B

    SGM2576/B
    Power Distribution Switch
     
    Power Distribution Switch
    GENERAL DESCRIPTION

    The SGM2576 and SGM2576B are integrated typically 100mΩ power switch for self-powered and bus-powered universal series bus (USB) applications.

    The SGM2576 and SGM2576B integrate programmable current limit to protect the upstream power supply from damage during over-current or short-circuit conditions. They have thermal shutdown that protects the device and load. 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.

    These devices employ soft-start circuit that minimizes inrush current in applications where highly capacitive loads are employed.

    SGM2576 and SGM2576B are available in a Green SOT-23-5 package. They are rated over the -40 to +85 temperature range.
