Quiet, Cool Motor-Driver ICs Homes in on Appliances

Toshiba Electronics Europe’s latest motor-driver ICs reflect the demand for compact design and quiet operation in applications such as home appliances and office automation equipment. The TB67S269FTG bipolar stepper-motor driver offers voltage up to 50 V and current of 2 A. Integrating the company’s ADMD motor-driving technology, the device reduces heat and increases efficiency. On-resistance is 0.8 Ω or less.

The TB67S269FTG offers high-resolution motor driving of 1/32 steps (max) to reduce vibration and noise. It’s housed in a small (7x7x0.5-mm) QFN48 package. Safety and reliability are enhanced by the inclusion of thermal and overcurrent shutdown circuitry.

Developed for use in cooling fans within home appliances, such as refrigerators, the TB67B001FTG, TB67B008FTG, and TB67B008FNG are three-phase, brushless, Hall sensorless driver ICs. They all feature a 150° wide-angle commutation drive and contribute to lower vibration and motor noise. A rotation speed up to 30,000 rpm can be achieved by means of high-speed pulse-width modulation and improved cooling. All offer an operating range from 4 to 22 V and a maximum output current of 3A.
