    Gate Driver selection for 80V TOLL MOSFETS

    Hi everyone,

    i have to design 3 phase inverter to drive induction motor. Input is directly connecting from the battery of 80V and 300A rating so i choose 80V 300A OPTIMOS POWER TRANSISTOR IPT012N08N5.
    So my question is how to choose gate drivers for this mosfet and what are the considerations i have to do to design 3 phase inverter.

    Thank you

    Hi Kiran,

    To protect the MOSFET the voltage rating should be larger than battery voltage rating, IPT015N10N5 would be better.

    For gate driver selection the frequency, gate peak current and voltage class must be considered, you can use Infienon online Finder tool to find a suitable driver:

    This app note about floating MOSFET gate driver for your reference:
