New four-channel automotive high-speed digital isolators

Toshiba Electronics Europe GmbH has released its first lineup of ten AEC-Q100 qualified, four-channel digital isolators. The new DCM34xx0 series has been designed to provide CMTI of 100kV/μs (typ.) at data transmission rates up to 50Mbps in applications like OBC and BMS for HEV and EV.

This new series of digital isolation devices employs the unique features of the company's proprietary magnetic coupling technology to deliver high CMTI of 100kV/μs (typ.) at supply voltages (VDD1=VDD2) from 3V to 5.5V with a common-mode voltage (VCM) of 1500V. This makes them highly resistant to common-mode electrical noise at the input and output nodes, ensuring they can supply stable equipment control signals for reliable equipment operations.

These four-channel devices provide flexible configuration options: four forward-only channels, three forward with one reverse channel, or two forward with two reverse channels, catering for various design needs. They supply low pulse-width distortion of just 0.8ns (typ.) and are suitable for multi-channel high-speed communication applications, including non-automotive uses such as I/O interfaces with SPI communications.

Devices in this series are offered in the 16-pin SOIC-16W package and provide stable operation in temperatures ranging from -40C to 125C.
