Part Number: DRV8873

Hi team,

My customer is using DRV8873 and they found that when the nfault will be pulled low for about 200ms after power up.

Do u think it is normal?

    Hello,

    I think you meant ~200us (according to scale on scope).  That is within the 1.5ms wake up time as specified in the datasheet.  Until the internal logic is active, the low signal on nFAULT is normal.

    Regards,
