Toshiba Releases Automotive Standard Digital Isolators Compliant With AEC-Q100

- Realize Stable Operation with High Common-mode Transient Immunity and High-Speed Data Communications -

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched its first lineup of 4-channel high-speed standard digital isolators for automotive applications. The new "DCM34xx01 Series” features 10 devices that support stable operation with high common-mode transient immunity (CMTI) of 100kV/μs (typ.)^[1] and high data transmission rate of 50Mbps (max)^[2]. All conform to the AEC-Q100 standard on the safety and reliability of automotive electronic components. Shipments start today.

Ensuring the safety and reliability of the on-board chargers (OBC) and battery management systems (BMS) used in hybrid-electric vehicles (HEV) and electric vehicles (EV) requires devices that ensure isolation and prevent noise-propagation. Automotive standard digital isolators provide solutions for the multi-channel high-speed communications and high CMTI these isolation devices require.

The new isolators use Toshiba's proprietary magnetic coupling type isolated transmission method to achieve a high CMTI of 100kV/μs (typ.). This delivers high level resistance to electric noise between input and output in isolated signal transmission, enables stable control signal transmission and contributes to stable equipment operation. In addition, a low-pulse-width distortion of 0.8ns (typ.)^[2] and a data-transmission rate of 50Mbps (max) are also achieved. The new products are suitable for multi-channel high-speed communication applications such as I/O interfaces with SPI communications.

Toshiba has already started mass production of Industrial standard digital isolators , and has now extended its product lineup to automotive equipment. Going forward, the company will increase the lineup of packages and number of channels in both areas. It will continue to provide high-quality isolation devices and photocouplers, that support the reliability and real-time data transmission required by automotive equipment.
