Dear, Sir.

My customer is looking for Full-step Stepping motor driver.

The driving current is so small as 67mA.

Regarding DRV8802-Q1,

Is it no problem to set ISENA/B chopping current as 67mA?

Best Regards,

Hi Sakai-san,

It is no problem to set the chopping current at 94mA. I would recommend using a sense resistor that creates approximately 300mV when the current threshold is reached. This should provide better current regulation.
