SPICE simulation of a stepper motor contrller. The control unit of stepper motor consists of 3 inputs and 4 outputs, INH that enables/disables the motor if low/high, CW that turns the motor clockwise/anticlockwise if high/low, and the CLOCK. The four outputs of the control unit drive the ULN2003A power driver accordly to the two phase drive sequence.Whole process of control unit design.
