Toshiba Electronics Europe has expanded its portfolio with the introduction of a series of two-channel, high-speed digital isolators designed to enhance the safety and reliability of hybrid and electric vehicles (EVs).
These AEC-Q100 qualified devices are part of the DCM32xx00 series and offer high common-mode transient immunity (CMTI) for stable operation.

The new digital isolators from Toshiba are engineered to support data transmission rates of up to 50Mbps and boast an impressive CMTI of 100kV/µs (typ.).
This makes them particularly suitable for critical automotive systems like on-board chargers (OBC) and battery management systems (BMS), which are essential components of hybrid electric vehicles (HEVs) and electric vehicles (EVs).
Utilising Toshiba’s proprietary magnetic coupling technology, the DCM32xx00 series ensures a high CMTI at supply voltages ranging from 3.0V to 5.0V, with a common-mode voltage (VCM) of 1500V.
This feature helps the devices to resist common-mode electrical noise, thus maintaining stable control signals for reliable operation of the vehicle’s equipment.
The two-channel isolators provide flexible configuration options and are designed to meet the requirements of high-speed communication applications, such as I/O interfaces with control area network (CAN) communications.
They offer low pulse-width distortion and are housed in a narrow 8-pin SOIC8-N package, ensuring stable performance in temperatures ranging from -40°C to +125°C.
Toshiba has also introduced a new series of four-channel high-speed standard digital isolators, the DCM34xx01 Series, in February.
These devices also feature a CMTI of 100kV/μs (typ.) and support data rates of up to 50Mbps, further demonstrating Toshiba’s commitment to the automotive sector.
Furthermore, Toshiba began offering engineering samples of its TB9084FTG, a MOSFET gate driver IC, in November last year.
This component is designed for three-phase brushless DC (BLDC) motors, which are increasingly preferred by automotive OEMs for their quiet operation and longevity in applications such as powered doors and adjustable seating.
