Shanghai, China, February 28, 2025- Toshiba Electronic Components and Storage Devices Co., Ltd. ("Toshiba") announced today the launch of its first 4-channel high-speed standard digital isolator product line for automotive applications, the "DCM34xx01 series". The new series includes 10 devices with high common mode transient suppression (CMTI) of 100 kV/μ s (typical value) [1] and high-speed data transmission rate of 50 Mbps (maximum value) [2], supporting stable operation. All devices comply with the AEC-Q100 standard for the safety and reliability of automotive electronic components. The 10 products in this series will support bulk shipping starting today.

In order to ensure the safety and reliability of on-board chargers (OBC) and battery management systems (BMS) used in hybrid electric vehicles (HEV) and electric vehicles (EV), devices that can ensure isolation and prevent noise propagation are needed. Vehicle mounted standard digital isolators can provide solutions for multi-channel high-speed communication and high CMTI required by current isolation equipment.

The new isolator adopts Toshiba's proprietary magnetic coupling isolation transmission method to achieve high CMTI of 100 kV/μ s (typical value). This not only achieves high tolerance for electrical noise between input and output in isolated signal transmission, but also ensures stable control signal transmission, which contributes to the stable operation of the equipment. In addition, these new products also have a low pulse width distortion of 0.8 ns (typical value) [2] and a data transmission rate of 50 Mbps (maximum value), making them suitable for multi-channel high-speed communication applications, such as I/O interfaces with SPI communication.

Toshiba's industrial standard digital isolator products are now in mass production, and its product line has expanded to the field of automotive equipment. In the future, Toshiba will increase the packaging types and channel quantities of products in these two fields, and continue to provide high-quality isolation devices and optocouplers to support the reliability and real-time data transmission required for in vehicle equipment.
