    145 Ohms stepper motor with S6J3200



      I would like to use a 145 Ohms motor with S6J3200.


      Max average current is 30mA @4.5V at room temp and 40mA @4.5V at -40°c, at this temp the resistance will decrease so that average current could be 45mA.


      is there a risk to damage the driver or will the driver limit itself to 40mA?


      Thank you for your feedback

          Dear Nicolas,


          Yes, maximum average current is 30mA @4.5V for room temperature and driver is limited to supply output current of max. 30mA.


          If we try to sink more current than the max rating from the device, voltage might drop to maintain the current levels which is not recommended for proper functionality.
