SGM25702

The SGM25702 high-side protection controller intelligently manages a high-side N-channel MOSFET during standard on/off transitions and fault conditions. It controls in-rush current through a constant rise time of the output voltage. A power good output indicates when the output voltage matches the input voltage and the MOSFET is fully conducting. The controller includes input UVLO with hysteresis and programmable input OVP. It features a remote on/off control via an enable input and a second safety redundancy enable through programmable UVLO. A single capacitor configures the delay time for initial start-up VGS fault detection, transition V_DS fault detection and continuous over-current V_DS fault detection. When a fault persists beyond the set delay, the MOSFET is deactivated until either the enable input or UVLO input is toggled low and then high again, restoring operation. 

The SGM25702 is available in a Green MSOP-10 package.
