DRV8301: PWM issue

Cherry Zhou

Part Number: DRV8301

Hi Team,

When using the DRV8301 to control a motor, the input upper PWM and the output PWM differ, causing problems with motor control. 

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hi Cherry, 

    Thank you for your question! 

    Can you clarify which phases/pins this issue is appearing on, and which are being shown in the waveform?

    And can you also provide the schematic and commutation method being used?

    Thank You and Best Regards,

    -Joshua
