Toshiba introduces new 4-channel (DCM34xx0 series) automotive high-speed digital isolators
Toshiba Electronics Europe GmbH has launched its first lineup of ten AEC-Q100 qualified, 4-channel digital isolators. The new DCM34xx0 series has been designed to provide common-mode transient immunity (CMTI) of 100kV/μs (typ.) at data transmission rates up to 50Mbps in applications like on-board chargers (OBC) and battery management systems (BMS) for hybrid-electric vehicles (HEV) and electric vehicles (EV).
Features
This new series of digital isolation devices leverages the unique features of Toshiba’s proprietary magnetic coupling technology to deliver high CMTI of 100kV/μs (typ.) at supply voltages (VDD1=VDD2) from 3.0 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, thereby ensuring they can deliver stable equipment control signals for reliable equipment operations.
These 4-channel devices offer flexible configuration options: 4 forward-only channels, 3 forward with 1 reverse channel, or 2 forward with 2 reverse channels, catering for various design needs. They provide 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 available in the 16-pin SOIC-16W package and offer stable operation in temperatures ranging from -40°C to 125°C.
