DRV8302: What is the maximum high and low level transition frequency of the gate of this IC?

Part Number: DRV8302
Other Parts Discussed in Thread: DRV8301,

Hi team,

The customer is wondering what is the maximum frequency at which the gate high and low level transitions of the DRV8301/8302 outputs can be made? Is it based on f_gate 200kHz(MAX) in datasheet 6.3 or on the time of each action in section 6.6? 

Could you help look into this case? Thanks.

Best Regards,

  • Hi Cherry,


    The maximum frequency that the gate high and low transitions can be made is based on f_gate which is calculated by dividing the total average gate drive current/6 by the total gate charge of the MOSFETS.

    For the DRV8301 and DRV8302 the total average gate drive current is 30 mA, which makes the equation: (30 mA/6)/ total gate charge.
