Toshiba Electronic Devices & Storage Corporation line of 2-channel high-speed standard digital isolators for automotive applications. The new "DCM32xx00 Series” features four 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 for the safety and reliability of automotive electronic components. Shipments start today.
The safety and reliability of on-board chargers (OBC) and battery management systems (BMS) in hybrid-electric vehicles (HEV) and electric vehicles (EV) require 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. A low-pulse-width distortion of 0.8ns (typ.)[2] and a data-transmission rate of 50Mbps (max)[2] are also achieved. The new products are suitable for 2-channel high-speed communication applications such as I/O interfaces with CAN[3] communications.
Toshiba already mass produces 4-channel automotive standard digital isolators, and has now extended its product lineup to 2-channel small SOIC8-N packages. Going forward, the company will expand its range of channels and packages for automotive and industrial equipment. It will continue to provide high-quality isolation devices and photocouplers that support the reliability and real-time data transmission required by automotive equipment.
