Automotive Stepping Motor Driver ICs

Toshiba’s line of stepping motor drivers is for a general multipurpose use and suitable for a wide range of automotive applications such as control of valves in refrigerant circuits etc., heads-up displays, and so on. These products have the advantage of being highly efficient at a simple clock input interface, microstep to reduce noise and vibration, and error detections such as a stall detection and an over current detection. Their reliability testing is fully qualified for AEC-Q100. Some good-quality solutions are offered by using Toshiba’s stepping motor drivers for automotive applications.
