Part Number:DRV8811
Hi,
My customer has a problem.
Some DRV8811s cannot regulate the motor current correctly at setting small chopping current.
Please see the below waveform.
Waveform1 is incorrect case.
Waveform2 is correct case.
These waveforms are one device's waveform. this shows that the problem only occur at setting small chopping current.
Could you tell me the reason of this problem, please?
-Waveform1
-Waveform2
Best regards,
Shimizu
