TIISO1042DWR

Overview

The ISO1042DWR is a galvanically isolated CAN FD transceiver that supports data rates up to 5Mbps. It provides high electromagnetic immunity and low emissions while isolating the CAN bus controller from the physical network. The device features a wide supply range of 1.71V to 5.5V on the controller side and a standard 4.5V to 5.5V supply on the bus side.

Why Choose This Part

This transceiver offers a high isolation voltage and a wide operating temperature range of -40degC to 125degC. Its 1.71V to 5.5V logic-side supply allows for direct interfacing with low-voltage FPGAs and microcontrollers without external level shifters. The device also includes fault protection and high common-mode transient immunity.

Applications

Getting Started

To evaluate this part, use the ISO1042DWEVM evaluation module which allows for easy testing of isolation and CAN FD performance. Ensure proper bypass capacitors are placed near the VCC1 and VCC2 pins, and follow TI's layout guidelines for maintaining creepage and clearance distances on the PCB. A CAN controller (integrated into an MCU or standalone) is required to drive the TXD and RXD pins.
