    Default Re: Calculating base resistor on mosfet AO3400A

    You can drive the MosFet directly from PIC as your frequency of activations is really slow.

    Gate driver is needed if your frequency is high. Also resistors or ferrite beads are also needed in higher frequency where ringing may interfere with normal operation.

    So, you are good to go without them.
