Stepper Motor Current Controller

Hi guys,

I need a little bit of help here. If I got a stepper motor driver with full flexibility on Overcurrent Protection(L6206), do I still need the PWM current controller L6506? What negative impact it will have that might affect the stepper motor?

Here’s some heads up from my findings:

Thanks a lot for the advice guys!
