Hi Team,

There is big noise for DRV8825. Measuring the motor coil waveform, but the customer does not see the pulse width change.

Thanks.

Hi Annie,

Can you provide more information, such as:

The VM voltage
A schematic of the connections to the device
The current waveforms
When does the noise occur, during operation or stopped?
The motor ratings (R, L, I)

It appears the pulse width is changing in the first image.The pulse width may not change much depending on the motor parameters.

Hi Rick,

The customer did not give me any response. You are able to close this thread now. Once there is feedback, I will let you know.

Thanks,
