New motor drivers from Toshiba deliver quiet and cool operation

Toshiba Electronics Europe (TEE) has announced the availability of several new motor driver ICs that reflect the demand for compact design and quiet operation in applications such as home appliances and office automation equipment.

The TB67S269FTG is a bipolar stepping motor driver that has been designed to offer a high voltage of 50V and current of 2A. High speed, high capability motor drives are required in printers, office automation equipment, ATMs, amusement machines and home appliances. At the same time, customer requirements for more compact, stylishly designed equipment are putting pressure on manufacturers to reduce size wherever possible. This is combined with a need to reduce heat within the equipment. TB67S269FTG reduces heat and increases efficiency by increasing the switching speed and adopting Toshiba’s ADMD motor driving technology. It has a low on resistance of 0.8O or less.

The TB67S269FTG offers high-resolution motor driving technology of 1/32 steps (max) to reduce vibration and noise. It is housed in a small (7x7x0.5mm) QFN48 package, which supports downsizing and cost reduction. 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. Smaller motors with quieter operation are now essential for use in eco-conscious home appliances. The new products, featuring a 150 degree wide-angle commutation drive, contribute to lower vibration and motor noise while a rotation speed up to 30,000rpm can be achieved by means of a high speed PWM and improved cooling. All offer an operating range from 4 to 22V and a maximum output current of 3A.

Package choices are: 36 pin, 5x5x0.9mm VQFN36 (TB67B001FTG), 24pin, 4x4x0.75mm WQFN24 (TB67B008FTG) and 24pin, 8.3×7.6×1.6mm SSOP24 (TB67B008FNG).

Mass production of all devices is scheduled to start in October 2014.
