Featured Product
Toshiba new DCM34xx0 4-channel automotive high-speed digital isolators
Key Features and Performance
- Toshiba has recently launched its first lineup of 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).
- 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.
