Toshiba Electronics Europe has introduced a high-voltage, high-resolution bipolar stepping motor driver with maximum ratings of 40V and 1.8A. The ultra-compact TB62269FTAG will suit applications ranging from home appliances and industrial automation to 3D printers and ATMs.
Supplied in a QFN32 package measuring just 5mm x 5mm x 1mm, the new device will help designers to realise PCB board space savings. A high-resolution 1/32 step (max.) resolution contributes to reduced vibration and noise, while an on-resistance of only 0.8Ω ensures energy-efficient operation and minimised heat dissipation.
The TB62269FTAG integrates error detection and protection functionality to support equipment safety and reliability. The protection functions comprise thermal shutdown and overcurrent shutdown circuitry alongside an error detection signal output.
