Toshiba Announces Series of High Voltage Single Chip Inverters for Brushless Motor Applications in Energy Saving Appliances

"Energy saving features of electronic equipment are becoming increasingly important, and employing DC motors in electronic equipment can significantly improve the energy efficiency of electronic equipment, thus saving energy, said Jeff Lo, business development manager, power semiconductors, for TAEC. "Toshiba's latest generation inverter drivers are offered in a new DIP26 package with lower thermal resistance than conventional inverter drivers, and contribute to the energy efficiency of brushless DC motor applications."

The series includes one 250V, 1A device, the TPD4121K, and eight 500V devices with output current ranging from 1A to 3A. The series provides designers with a selection of integrated functions to meet various application requirements, including Hall sensor input or six inputs, three phase matrix logic, power management circuits, level shift drivers, over current protection, over temperature protection and under voltage protection. (Please see product specification table below for part numbers and supported features of each.)

The Toshiba series of high voltage IPD single chip inverters utilize silicon on insulator (SOI) process to enable use of the DIP26 package, which has a maximum thickness of 3.8mm, more than 25 percent thinner than the previous generation 5.2mm (max.) F23 package. Each of the nine devices incorporate bootstrapping diodes, so no high-side driving power is required due to bootstrapping. For ease of layout on a printed circuit board, high voltage power pins and low voltage signal pins are on opposite sides of the package. The control pins have a pitch of 2.0mm and the high voltage pins feature wide clearance of 3.8mm.
