Overview

The ISO1042DWVR is a high-performance, galvanically isolated CAN FD transceiver supporting data rates up to 5 Mbps. It features a wide supply voltage range from 1.71V to 5.5V on the logic side, allowing for direct interfacing with 1.8V, 2.5V, 3.3V, and 5V controllers. This device provides robust protection with a 70V DC bus fault rating and a common-mode voltage range of +/-30V.

Why Choose This Part

This transceiver offers superior protection with a +/-70V bus fault voltage and 16kV HBM ESD tolerance, reducing the need for external protection components. It ensures high signal integrity in noisy environments through a high common-mode transient immunity (CMTI) of 100 kV/us and low loop delays of 152 ns.

Applications

Industrial Automation
Used in PLC and motor control networks requiring high CMTI and isolation to protect low-voltage controllers from high-voltage transients.
Electric Vehicle Charging
Ideal for communication between charging stations and vehicle systems where safety-rated isolation is mandatory.
Solar Inverters
Facilitates reliable CAN communication in power conversion systems with high switching noise, thanks to its 100 kV/us CMTI.
Battery Management Systems (BMS)
Provides isolated monitoring and communication across high-voltage battery stacks in energy storage systems.

Getting Started

Designers can evaluate the performance of this IC using the ISO1042DWEVM evaluation module. Ensure VCC1 is supplied with the logic level of your controller (1.71V to 5.5V) and VCC2 is provided with a standard 5V supply for the CAN bus side. Proper PCB layout with clear isolation creepage and clearance distances is essential to maintain the device's safety certifications.
