TJA1057GT/3J
Overview
The TJA1057GT/3J is a high-speed CAN transceiver designed for automotive and industrial applications, providing an interface between a CAN protocol controller and the physical two-wire CAN bus. This AEC-Q100 qualified device supports data rates up to 5 Mbps, making it suitable for CAN FD (Flexible Data-rate) networks. It features a Vio pin for direct interfacing with 3.3V or 5V microcontrollers and includes comprehensive protection against transients and ESD.
Why Choose This Part
The part excels with its 210 ns propagation delay and 5 Mbps data rate capability for high-speed CAN FD throughput. It provides superior 8 kV IEC ESD protection and a wide operating temperature range up to 150 degrees Celsius. Additionally, its TXD dominant time-out function prevents bus lockup caused by hardware or software failures.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, interface the TXD and RXD pins with a CAN controller's peripheral while providing a 5V supply to Vcc. Use the Vio pin to match the logic level of your microcontroller, typically 3.3V or 5V. Ensure the CAN bus is properly terminated with 120-ohm resistors at both ends of the physical network for signal integrity.
