70V Fault-Protected Isolated CAN FD Transceiver IC with 5Mbps Data Rate and Reinforced Isolation (SOIC-8)
The ISO1042BDWVR is a high-performance isolated CAN transceiver IC designed for robust and safe communication in industrial, automotive, and high-voltage environments. It provides galvanic isolation between the CAN bus and system logic, protecting sensitive circuits from high voltage transients and noise. Fully compliant with ISO 11898-2:2016, the device supports both Classical CAN and CAN FD with data rates up to 5 Mbps, enabling faster and more efficient data transfer in modern communication systems.
Built with a silicon dioxide (SiO2) isolation barrier, the IC offers high insulation capability with up to 5000 VRMS withstand voltage and a wide working voltage range. It features +-70V bus fault protection and a wide +-30V common-mode range, ensuring reliable operation in electrically harsh environments. Enhanced electromagnetic compatibility (EMC) performance helps meet stringent system-level requirements for ESD, EFT, and surge protection. Ideal for use with isolated power supplies, this device prevents noise propagation and ensures stable communication across isolated domains.
