Overview

The TJA1051T/3/1J is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. This AEC-Q100 qualified device is designed for high-speed CAN applications in the automotive and industrial sectors, supporting data rates up to 5Mbps. It features a dedicated Vio pin that allows for direct interfacing with microcontrollers operating from 3V to 5V without external level shifters.

Why Choose This Part

The transceiver offers excellent ESD protection and high electromagnetic immunity with low emissions, simplifying compliance with automotive standards. Its predictable behavior during undervoltage conditions and the TXD dominant time-out function prevent bus blockage, ensuring system-level reliability.

Applications

Automotive Body Control
Ideal for 12V and 24V vehicle systems requiring reliable CAN communication for ECU networking.
Industrial Automation
Used in PLC communication and factory automation networks requiring high electromagnetic immunity (EMI).
CAN FD Networking
Supports CAN Flexible Data-rate (FD) fast phase communication up to 2 Mbit/s for high-bandwidth telemetry.
Battery Management Systems
Provides the robust physical layer needed for communication between battery monitoring ICs and the main controller.

Getting Started

To implement this device, connect the TXD and RXD pins to your CAN controller and provide 5V to Vcc; use the Vio pin to match your MCU logic level (3V to 5V). Ensure a 120-ohm termination resistor is present at the ends of the bus, and place a decoupling capacitor close to the Vcc pin for stable high-speed performance.

Also Consider

MCP2562-E/SN MCHPMicrochip Technology - A popular alternative that also includes a Vio pin for level shifting and features similar 5Mbps performance.
ISO1050DUBR TITexas Instruments - Consider this if your application requires galvanic isolation between the CAN controller and the physical bus.
