Part Number:DRV8833
Hi team,
My customer is using our DRV8833 to drive a stepper motor in full step mode. VM is supplied by a 3.7V battery. When the Risense=1ohm, the chopping current should be 200mA and the current waveform is OK. But when they change the Risense to 0.5ohm to make the chopping current to be 400mA, the current waveform is distorted. Please see below picture for the 200mA and 400mA chopping current. Could you please help analyze the root cause? Thanks.
Best regards,
Wayne
