The NXP TJA1041 is a cutting-edge high-speed Controller Area Network (CAN) transceiver that serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. Designed for high-speed automotive networking, it is capable of speeds up to 1 Mbps. The TJA1041 is an evolution of the classic TJA1040, bringing improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance to the table, ensuring reliable communication in the demanding automotive environment.
Key Features
- High Speed: Supports CAN transmissions with speeds up to 1 Mbps.
- Low Power Mode: Features a very low current standby mode with bus wake-up capability.
- Improved Protection: Offers robust EMC and ESD performance, essential for automotive applications.
- Error-Free Communication: Includes features like differential receiver with wide common-mode range for high immunity against electromagnetic interferences.
- Compatibility: Fully compatible with the "ISO 11898-2:2016" standard and previous versions.
Applications
The TJA1041 is primarily used in automotive electronics for applications such as powertrain systems, chassis control modules, gateway modules, and body control units. Its robust design also makes it suitable for industrial automation systems, medical equipment, and other high-integrity serial data communication applications.
Enhanced Functionality
One of the standout features of the TJA1041 is its enhanced fail-safe features which include a 'silent mode' in which the transmitter is disabled, allowing nodes to be connected to the bus without affecting the data traffic. Additionally, the TJA1041 incorporates a bus pin short-circuit proof to battery and ground, and an undervoltage detection on the VCC supply pin.
Package and Supply
The device is available in a leadless HVSON14 package, which is suitable for use with a standard SMD process. It is designed to withstand the rigors of the automotive environment, offering a wide operating temperature range from -40°C to +150°C. The TJA1041 requires a supply voltage of 4.5 V to 5.5 V and is optimized for 5 V automotive systems.
