To ensure the safety and reliability of factory automation equipment, isolation devices are needed to ensure insulation and prevent noise propagation. Toshiba provides digital isolator solutions to meet the requirements of industrial applications in higher speeds, multi-channel signal communication, and high CMTI.
The new product adopts Toshiba's proprietary magnetic coupling insulation transmission method, which can provide 100kV/ μ High CMTI of s (minimum value) [1]. This not only achieves a high tolerance for electrical noise between input/output in isolated signal communication, but also contributes to stable control of signal transmission and equipment operation. The digital isolator has a low pulse width distortion of 0.8ns (typical value) and a high-speed data rate of 150Mbps (maximum value), making it suitable for multi-channel high-speed communication applications, such as I/O interfaces for SPI communication.
For 50 years, Toshiba has been providing its customers with optocouplers - isolation devices that ensure insulation performance through optocoupling. Looking ahead, in addition to optocouplers, Toshiba will also expand its high-speed four channel digital isolator product line, increase the number of channels and packages, and provide high-quality insulation devices to support reliable and real-time data transmission required for industrial equipment control.
