High speed, high performance motor drives are required for applications including 3D printers, office automation equipment, banking terminals such as ATMs, banknote identification machines, amusement machines, and home appliances. In parallel, the downsizing of equipment is being accelerated by customer demand for space-saving equipment with excellent design. Measures to reduce products’ internal heat and power consumption are also growing in importance.

The new motor driver has a QFN32 package, smaller than the QFN48 package housing Toshiba’s current product, “TB62269FTG.” This size reduction will contribute to space saving on the PCB.

Toshiba will continue to enhance its product line-up and to meet diverse requirements for motor drive applications.

Main Features of New Product

1. Low heat generation

Heat generation is reduced by low on resistance (0.8Ω or less, upper + lower).

2. Low vibration and low noise

High-resolution 1/32 step (max.) motor drive technology reduces vibration and noise.

3. Small package

Heat treatment of the equipment and the module can be simplified by adopting a small, high-heat-radiation QFN32 package. This also downsizes the IC and reduces the cost.

4. Built-in error detection circuits

A thermal shutdown circuit and an overcurrent shutdown circuit contribute to equipment safety and reliability with the signals they output at the design stage.


3D printers, amusement machines (pachinko and slot machines), home appliances (refrigerators and air conditioners), industrial equipment (banking terminals such as ATMs), office and factory automation equipment)
