Using Dual H-Bridge Motor Driver as Stepper Motor Driver

This is how to use my designed of Dual H-Bridge Motor Driver as Stepper Motor Driver with half stepping sequence.



As half stepping require two phases to be energize at any given time, OUT1 & OUT2 or OUT3 & OUT4 should not be simultaneously use on any two phases that will be on at the same time.
One possible combination of wiring will be:
Stepper Motor   >>   H-Bridge Motor Driver
Phase 1   >>   OUT1, driven by IN1
Phase 2   >>   OUT3, driven by IN3
Phase 3   >>   OUT2, driven by IN2
Phase 4   >>   OUT4, driven by IN4
