TJA1051T/3,118
Overview
The TJA1051T/3 is a high-speed CAN transceiver that provides an interface between a Controller Area Network protocol controller and the physical two-wire CAN bus. This specific variant is AEC-Q100 qualified and supports CAN FD data rates up to 5 Mbit/s, making it suitable for modern automotive and industrial networking requirements. It includes a dedicated VIO pin for direct interfacing with low-voltage microcontrollers ranging from 3V to 5V.
Why Choose This Part
The device offers excellent electromagnetic compatibility with low emissions and high immunity without the need for an external common-mode choke in many cases. It features ideal passive behavior when unpowered, ensuring it does not load the bus, and includes comprehensive protection against transients and short circuits.
Applications
Getting Started
To implement this part, connect the TXD and RXD pins to your MCU's CAN controller and provide 4.5V to 5.5V on VCC. The /3 version requires a voltage on the VIO pin to set the I/O logic levels; ensure this matches your microcontroller's supply voltage. Place a 100nF decoupling capacitor close to the supply pins and follow standard differential pair routing for the CANH and CANL bus lines.
