The NXP TJA1044GT is a high-speed CAN transceiver that serves as an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. Designed to operate in harsh automotive and industrial environments, the TJA1044GT provides robust communication with improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance.

Key Features

• ISO 11898-2:2016 Compliant: The device adheres to the latest CAN standard, ensuring reliable communication at data rates up to 1 Mbit/s.
• Low Power Modes: With a focus on energy efficiency, the TJA1044GT features a Standby mode and a Sleep mode, reducing power consumption when the network is idle or when the device is not in active use.
• Bus-Fault Protection: The transceiver is capable of withstanding bus-fault conditions of ±58V, safeguarding the device against transients and enhancing system reliability.
• Improved EMC Performance: The device is designed with EMC enhancements, minimizing radiated emission and ensuring stable operation in electrically noisy environments.
• Fail-Safe Behavior: In the event of a failure, such as loss of power supply or ground, the TJA1044GT will automatically disable its driver to prevent any detrimental effect on the CAN bus.

Applications

The TJA1044GT is ideal for automotive applications, including powertrain, chassis, safety, and driver assistance systems. It is also well-suited for industrial automation, where reliable data communication is critical.

Package and Temperature Range

The transceiver is available in an 8-pin SOIC package (TJA1044GT/3), which is lead-free and RoHS compliant. It operates over an extended temperature range from -40°C to +125°C, accommodating the demanding conditions of automotive and industrial applications.
