    Hello,

    I have a IXDD614 MOSFET driver (http://www.clare.com/home/pdfs.nsf/www/IXD_614.pdf/$file/IXD_614.pdf) and I want to use it to drive a IR hexfet power mosfet (http://www.irf.com/product-info/datasheets/data/irlb3036pbf.pdf). The mosfet will be flowing upwards of 60A through it for a period of 300ms (I am not PWMing the driver). what would I need in terms of outside circuitry to make sure the driver works properly? Like do i need decoupling caps or output series resistance?

    Thanks

    You always use 0.1μF decoupling caps directly from the driver voltage supply to the ground pin. Also there should be a short ground path between the driver and the MOSFET source.

    A small resistor in series with the gate is often suggested to minimize ringing in the signal. Values of 4.7Ω to 27Ω are typically used.
