Hi Pao,

There is no builtin filter in DRV10863, you can connect simple RC filter externally to filter out spikes.

Do you face any problem driving device with spikes on PWM signal ?

Hi Krushal,
Sorry, My customer mistakenly think TI have same bug.
My competitor is Rohm. The sensor mode is voltage mark.
If it have shift or spike, It will shut down or jitter.

DRV10863 is current sensor control, right??

Hi Krushal,
Thank you for your support.
Customer want to know whether DRV10866 could replace DRV10863 directly. Could you help to advise this information?
I can't find DRV10863 datasheet from TI web.

Hi Pao,

Yes, DRV10866 can replace DRV10863 directly, it is pin to pin compatible and it has same package.
