High speed, high performance motor control is essential for printers, office automation equipment, banking terminals such as ATMs, cash dispensers, amusement machines, and home appliances. Recent customer demand for stepping motor control have centered on demands for lower noise and vibration, as equipment is used in increasingly diverse environments.

The key to reducing noise and vibration in a stepping motor is highly efficient operation with accurate current control. Adoption of Selectable Mixed Decay (SMD), a current adjustment function, allows the new IC to reduce noise and vibration by selecting the appropriate SMD setting suitable for the motor.

Use of Toshiba’s state-of-the-art high voltage analog process also improves performance, as it allows the driver to achieve a 50V maximum rating and integrates low on resistance MOSFETs for the motor output to operate at 0.49 Ω (upper + lower: typ.).
