Frequently Asked Questions
What is the isolation voltage rating of the ISO1050DUBR?
The ISO1050DUBR provides 5kVrms reinforced isolation between the CAN bus side and the logic/controller side, making it suitable for industrial and medical applications where high-voltage isolation is required to protect sensitive circuitry.
What CAN bus data rate does the ISO1050DUBR support?
The ISO1050DUBR supports CAN bus data rates up to 1Mbps, fully compliant with the ISO 11898 standard. This makes it ideal for high-speed industrial automation, automotive test systems, and real-time control networks.
Is the ISO1050DUBR compatible with 3.3V microcontrollers?
Yes, the ISO1050DUBR is compatible with both 3.3V and 5V logic levels on the controller side, allowing direct interfacing with modern low-voltage microcontrollers and FPGAs without additional level-shifting components.
What bus fault protection does the ISO1050DUBR offer?
The ISO1050DUBR features ±70V bus fault protection on the CAN bus lines, far exceeding the ISO 11898 requirement of ±36V. This robust protection ensures reliable operation in harsh industrial environments with high-voltage transients.
