In order to develop motor driver ICs that will help reduce the power consumption and acoustic noise of motor applications, it is necessary to improve the speed and performance of AD converters and power transistors and to increase logic integration density. However, it is not practical to try to address all these needs using conventional technologies because doing so will cause the die size to increase and thus impact the overall cost.
Instead, Toshiba has adopted the state-of-the-art BiCD/CD process, an industry-leading 0.13-μm high-voltage mixed-signal process with the world's lowest on-resistance (RonA). Thanks to the significant increase in circuit density, new driver ICs will help improve motor performance with smaller footprints and lower costs and thus meet exacting customer needs.
Since 1980, Toshiba has accumulated over 30 years of experience in the development of motor driver ICs. Toshiba has continuously led the industry, establishing a highly successful track record. During this period, Toshiba has used each new generation of processes to enhance performance and add new features for ensuring smooth and quiet motor operation. Toshiba has continued to improve the IC performance. Recent additions to our product portfolio include motor driver ICs with various safety features for detecting abnormal conditions, such as overcurrent, overtemperature and faulty behavior. These ICs contribute to improving the motor reliability. Furthermore, Toshiba has been integrating peripheral circuit functions onto the same chip to reduce the external parts count and thus the overall cost.
To meet a wide range of market needs, Toshiba offers over 100 motor driver ICs for brushless motor, stepping motor and brushed motor applications. Our product portfolio includes many motor driver ICs that are specifically designed to address the market's growing needs, such as sine-wave driver ICs for air-conditioner fan motor applications that integrate an IPD and the controller section of a motor driver in a system-in-package (SiP) and single-chip driver ICs for small fan motor applications in refrigerators, ventilators, etc. Additionally, Toshiba is actively developing new motor driver ICs to expand its product portfolio.
Toshiba will continue to use the state-of-the-art process to increase the levels of integration, improve performance, reduce size and cut costs. At the same time, Toshiba stays in close contact with its customers to better understand their needs and respond to them in a timely fashion.
Moreover, Toshiba will cooperate with the Corporate Manufacturing Engineering Center, which is involved in the R&D of electrical motors to actively offer new proposals for improving motor performance and to develop new trend-setting and industry-leading technologies.
