... During normal commutation of a unipolar stepper motor, mutual coupling between the motor windings can force the outputs of the UCN5804B below ground. This condition will cause forward biasing of the collector-to-substrate junction and source current from the output. For many L/R applications, this substrate current is high enough to adversely affect the logic circuitry and cause misstepping ...
