Overview

The ISO1042DWV is a galvanically-isolated CAN transceiver designed to meet ISO11898-2 (2016) physical layer standards. It supports both CAN FD data rates up to 5 Mbps and classical CAN, while providing 70V bus fault protection and high common-mode transient immunity (CMTI).

Why Choose This Part

This transceiver offers a high bus fault protection of 70V and a wide common-mode voltage range of +/-30V, significantly increasing robustness against wiring errors and ground shifts. Its integrated isolation barrier eliminates the need for separate optocouplers, reducing PCB area and simplifying compliance with safety standards.

Applications

Electric Vehicle Charging Systems
Provides high-voltage isolation between the vehicle's CAN bus and internal charging control electronics.
Industrial Automation
Reliable communication in noisy factory environments requiring isolation between distributed motor controllers.
Grid Infrastructure
Used in solar inverters and energy storage systems to protect low-voltage control logic from high-voltage DC bus transients.

Getting Started

Engineers can evaluate this IC using the ISO1042DWEVM evaluation module, which allows for signal integrity testing and transient performance verification. Ensure that the VCC1 (logic side) and VCC2 (bus side) are powered by independent, isolated power supplies to maintain the integrity of the isolation barrier.
