Can I give gate source signal from the gate driver to one of the gate source pair and leave the other pair open for the inverter design? If not then please let me know what can be the possible issues?

    Hello Aradhya,

    Can you please confirm you're referring to the XM3 module family, CAB320M17XM3 correct? Thanks!

    Hi Aradhya,

    The two gate pins and the two source pins are connected internally in the XM3 module. You have the option to only supply the VGS signal to 1 pair of pins and the module will function. For the best performance and reliability, we recommend that both pairs of pins are utilized.

    Best Regards,

    Austin C.

    Will the open pin be affected by some unwanted signal
