Overview

The ISO1042QDWRQ1 is an AEC-Q100 qualified, galvanically isolated CAN FD transceiver designed for automotive and industrial applications. It supports data rates up to 5Mbps and provides a high level of protection with a +/-70V DC bus fault tolerance and 100kV/us common-mode transient immunity.

Why Choose This Part

This transceiver features an impressive +/-70V bus fault protection and a wide common-mode voltage range of +/-30V, significantly increasing system robustness. It also supports a wide primary-side supply range from 1.71V to 5.5V, allowing direct interfacing with low-voltage FPGAs and microcontrollers without level shifters.

Applications

Electric Vehicle (EV) Battery Management Systems
Provides essential isolation between high-voltage battery stacks and low-voltage control electronics while maintaining reliable CAN communication.
Inverters and Motor Controllers
High CMTI performance allows the transceiver to operate in noisy environments near high-speed switching power stages.
Industrial Automation
Protects sensitive PLC and controller inputs from ground loops and industrial transients in long-distance bus deployments.
