    I am using SI9933 Vishay's Dual P channel mosfet in one of my design..
    I am using only one mosfet and the other mosfet is left unconnected. Can I leave both Source Gate and Drain unconnected.??? Or should I ground them ???
    PLs help

    I wouldn't worry about it. With gates all the digital gates are powered up, whether they are used or not, and must be tied down. The spare MOSFET is getting no power.
