Toshiba Electronics Europe has recently rolled out five stepping motor control drivers. The next generation drivers are designed using the company's BiCD 130nm mixed-signal process technology, providing excellent Ron per unit area. The result is highly integrated, low-power devices with the industry's highest voltage and current combinations, (Part TB67H302HG) and compact footprints (Parts TB67S213FTAG, TB67S215FTAG, TB62261FTAG and TB62262FTAG). These devices are well suited for a variety of applications such as printers, ATM, robotics, process control machines, and medical equipment.

Today's printers, ATMs, and process control machines require high speed, high torque, and high precision for efficient long-term operation. The new Toshiba stepping motor control drivers satisfy these requirements through exceptional design, superior performance, and optimum packaging. For high-power applications, the TB67H302HG combines the highest voltage and current combination in class and is rated 50V/5.0A. The device is supplied in a heat sink-mountable HZIP25 package.

The TB67S213FTAG and TB67S215FTAG devices are rated 40V/2.5A and are housed in a compact QFN-36x6mm package for medium-power applications. They also reduce power consumption by 50 per cent compared to previous generation devices. The TB62261FTAG and TB62262FTAG devices are rated 40V/1.5A and also come in a QFN-36 6x6mm package for low-power applications. All of the new motor control drivers have a mixed-decay mode, which improves the response characteristics of the motor drive current by changing the current path, for optimum motor driving. The QFN36 6x6mm packaged devices are also around 30 per cent smaller than surface mount devices of similar performance. As such, these motor control drivers can be integrated in motor control boards to reduce customer design costs.
