High speed and high performance motor control and lower power consumption are required for applications that include 3D printers, office equipment, banking terminals such as ATMs, cash dispensers, amusement machines, and home appliances. To meet these conflicting requirements, Toshiba has applied its original current optimization technology, AGC, to a new motor driver IC that achieves a large current drive (50V/5A rating).

Recent years have seen increasing demand for equipment offering higher accuracy and quieter operation. Toshiba’s new motor driver IC realizes high accuracy and low vibration by delivering 128 micro steps, realizing a much higher definition than conventional 32-step devices. It also uses SMD, a current adjustment function, to reduce noise and vibration effectively during motor drive by selecting the SMD configuration best suited for each motor.

Use of another Toshiba original current detection technology, ACDS, reduces the number of components required for driver control, contributing to lower system costs and improved flexibility in board pattern design.
