Toshiba Electronic Devices & Storage Corporation has introduced the DCM32xx00 Series, a line of 2-channel high-speed standard digital isolators for automotive applications. The series includes four devices, all compliant with the AEC-Q100 standard for automotive electronic components. Shipments began on June 19, 2025.
These isolators are designed for on-board chargers (OBC) and battery management systems (BMS) in hybrid-electric vehicles (HEV) and electric vehicles (EV), providing isolation and noise suppression. The devices use Toshiba’s proprietary magnetic coupling transmission method, achieving a common-mode transient immunity (CMTI) of 100kV/μs (typical) under test conditions of 4.5 to 5.5V supply voltage, 1500V common-mode voltage, and operating temperatures from -40 to 125°C. They support a data transmission rate of up to 50Mbps (maximum) and a pulse-width distortion of 0.8ns (typical) under the same test conditions.
The DCM32xx00 Series is suitable for 2-channel high-speed communication applications, such as I/O interfaces with Controller Area Network (CAN) communications. The series offers configurations with one forward and one reverse channel or two forward channels without a reverse channel, packaged in small SOIC8-N formats. Toshiba also produces 4-channel automotive digital isolators and plans to expand its range of channels and packages for automotive and industrial applications.
