Toshiba Electronics Europe GmbH has introduced the DCM32xx00 series, a new family of AEC Q100 qualified two channel digital isolators designed for use in automotive systems such as on board chargers and battery management systems in both hybrid and fully electric vehicles. These isolators employ Toshiba’s proprietary magnetic coupling technology, delivering a typical common mode transient immunity of 100 kilovolts per microsecond. This high CMTI ensures robust signal isolation in environments with significant electrical noise and rapid voltage transients.

The DCM32xx00 series supports data transmission rates up to 50 megabits per second, ensuring reliable high speed communication between safety critical subsystems. The devices operate across a supply voltage range of three to five volts on both input and output sides, with a maximum common mode voltage of 1500 volts. This allows for integration into a wide variety of automotive electrical architectures. Designers can select from two channel configurations, either two forward channels or one forward and one reverse channel, providing flexibility for both unidirectional and bidirectional data paths.

Pulse width distortion is minimized to 0.8 nanoseconds typical, supporting precise timing for high speed protocols such as those used in control area network communications. The isolators are packaged in a narrow body eight pin SOIC package, which supports compact printed circuit board layouts and straightforward integration. The series is rated for operation across the full automotive temperature range from minus forty to plus one hundred twenty five degrees Celsius, meeting reliability requirements for both automotive and industrial environments.

By combining high CMTI, low propagation delay, and robust packaging, the DCM32xx00 series enhances the safety and reliability of signal isolation in applications where fast switching and high voltage differentials are present. Toshiba will continue to expand this product line with additional channel counts and package options to meet the evolving needs of advanced automotive and industrial systems.
