The TJA1051T/3,118 is a high-speed CAN (Controller Area Network) transceiver designed by NXP Semiconductors. It serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. This transceiver is particularly well-suited for automotive applications and industrial automation systems where robust communication and high noise immunity are required.

Key Features

• High-Speed CAN Interface: Supports the ISO 11898-2:2016 standard, allowing for data transfer rates up to 1 Mbit/s.
• Improved Electromagnetic Compatibility (EMC): Enhanced features for reducing electromagnetic emissions and improving immunity to electromagnetic interferences.
• Low Power Mode: Features a very low current standby mode with remote wake-up capability, making it suitable for power-sensitive applications.
• Transmit Data (TXD) Dominant Time-out Function: Prevents the bus line from being driven to a permanent dominant state due to a faulty controller.
• Thermal Protection: Incorporated thermal protection disables the transmitter in the event of a short-circuit at the CANH or CANL outputs.
• Bus Pins Protected Against Transients: Provides additional resilience in harsh electrical environments.

Applications

The versatile nature of the TJA1051T/3,118 makes it a prime choice for a broad range of applications where a reliable CAN communication interface is needed. It is commonly used in:

• Automotive networks, including body control modules, powertrain, and infotainment systems.
• Industrial control systems, such as sensor networks and motor control units.
• Heavy machinery and agricultural equipment for reliable onboard diagnostics and control.
• Medical equipment requiring secure and robust data communication.
