Overview

The ISO1042BDWVR is a galvanic isolated CAN FD transceiver that supports data rates up to 5Mbps. It features a wide supply voltage range from 1.71V to 5.5V on the controller side and a standard 4.5V to 5.5V supply on the bus side. This device provides reinforced isolation to protect low-voltage microcontrollers from high-voltage transients in harsh electrical environments.

Why Choose This Part

The device offers a high common-mode transient immunity (CMTI) and a high bus-fault protection voltage of +/- 70V. Its wide input voltage range on the VDD1 side allows for direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic without external level shifters. The reinforced isolation barrier ensures long-term reliability and safety compliance in high-voltage applications.

Applications

Industrial Automation
Protects PLC and sensor networks from ground loops and electrical noise in factory environments.
Electric Vehicle Charging
Provides safety isolation for CAN communication between the high-voltage battery management system and charging stations.
Solar Inverters
Used for robust communication between power stages and central control units in grid-tied energy systems.
Motor Drives
Facilitates reliable CAN FD networking in high-power motor control systems with significant EMI.

Getting Started

Designers can evaluate this transceiver using the ISO1042DWEVM evaluation module. Connect the VDD1 pin to your microcontroller logic level and VDD2 to a 5V supply, ensuring proper decoupling capacitors are placed close to the pins. Standard CAN controllers can interface via the TXD and RXD pins for immediate protocol testing.
