Shanghai, China—Toshiba Electronic Devices & Storage Corporation (“Toshiba”) today announced the launch of a new series of dual-channel high-speed standard digital isolators for automotive applications—the “DCM32xx00 Series.” This series includes four devices that enable stable operation with a high common-mode transient immunity (CMTI) of 100kV/μs (typical) and a high-speed data transfer rate of 50Mbps (maximum). All components comply with the AEC-Q100 automotive electronic device safety and reliability standards and are now available for mass production shipments.
To ensure the safety and reliability of on-board chargers (OBC) and battery management systems (BMS) in hybrid electric vehicles (HEVs) and pure electric vehicles (EVs), the required components not only need to ensure isolation but also need to have the capability to prevent noise propagation. Toshiba's latest automotive-grade digital isolators can provide the necessary multi-channel high-speed communication for these isolation components and...High CMTIProviding exceptional solutions.
The latest standard digital isolators adopt Toshiba's proprietary magnetic coupling isolation transmission method, achieving a high CMTI of 100kV/μs (typical value). This enables a high level of noise immunity between input and output during isolated signal transmission, ensuring stable control signal transmission and contributing to the reliable operation of devices. Additionally, they achieve a low pulse width distortion of 0.8ns (typical value) and a data transfer rate of up to 50Mbps (maximum value). These new products are suitable for dual-channel high-speed communication applications, such as I/O interfaces supporting CAN communication.
Toshiba'sFour-channel automotive-grade standard digital isolatorMass production has begun, and its product line has now expanded to include dual-channel small SOIC8-N packages. In the future, Toshiba will further broaden the range of channels and packages for automotive and industrial equipment, and will continue to provide high-quality isolators and optocouplers to meet the reliability and real-time data transmission requirements of automotive equipment.
