The driver IC contains two [[H-Bridge]]s and additional circuitry which gives you a simplified control: Has one input to do steps and a second input determining the step's direction. So only 2 input lines are needed here. | ||
A modern stepper motor driver does much more than just the described above. It also will adjust the current through the coils so the motor is powerful at high and low speeds (to do this for high speed it requires more voltage). Or is able to do so called micro-steps - steps which are between the given physical steps of a motor. Half-Steps means you have twice as much steps, quarter means four times ans much, ... | A modern stepper motor driver does much more than just the described above.
