Tool/software:

Hi team,

If customer sets DRVOFF to 1. How will the MOSFETs be turned off? With IDRVN or passive pulldown? Thanks!

Best Regards

    Hi team,

    Add some background and further questions updated from customer:

    1. If customer turns off MOSFET by set EN_DRV to 0. How will the MOSFETs be turned off? With IDRVN or passive pulldown?
    2. If MOSFET is turned off by passive pulldown, customer is concerned that the turn-off is too slow and causes MOSFET to be damaged when load current is large because of heat.

    Best Regards
