DRV8818: Ask DRV8818 pin to pin solution, I want to make a PCB board that I can control 5V/12V/24V Step Motor by changing the driver IC

Hello,

If I want to make a PCB that I can control 5V/12V/24V Step Motor by changing driver IC. Is there any pin to pin solution of DRV8818?  After remount the driver ic and change power voltage, I can control different step motor(different input voltage)

    Hi George,

    Do you need to change the supply voltage?

    The DRV8818 and most modern stepper motor controls use current regulation to control the stepper motor. Using current regulation allows the supply voltage of the controller to be much higher than the rated stepper voltage.

    If you do need to change the supply voltage, we do not have a pin to pin solution for the DRV8818. The DRV8818 can operate from 8V to 35V.
