TJA1043TK/1Y

Drivers, Receivers, Transceivers Overview

The TJA1043TK/1Y is a high-speed CAN transceiver from NXP Semiconductors, designed for automotive applications. It interfaces between a CAN protocol controller and the physical two-wire bus. The device supports data rates up to 5 Mbit/s in the CAN FD fast phase, compliant with ISO 11898-2:2016 and SAE J2284 standards. It operates on a VCC supply of 4.5 V to 5.5 V and VIO of 2.8 V to 5.5 V. Key electrical parameters include a typical supply current of 48 mA in normal mode (dominant) and 0.75 µA in standby/sleep modes. It features ESD protection of ±8 kV per IEC 61000-4-2 and withstands bus voltages up to ±58 V. The component is housed in an HVSON14 package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with required environmental conditions and voltage levels before integration. Cross-reference the part number with authorized distributors to confirm authenticity and traceability. Check for any recent revisions to the datasheet that may impact pinout or electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for designs requiring robust EMC performance and fail-safe diagnostics. Consider the HVSON14 package for improved thermal dissipation and Automated Optical Inspection capabilities. Evaluate the need for CAN FD support up to 5 Mbit/s and the specific low-power requirements of the node. Ensure the microcontroller interface voltage aligns with the VIO supply range for direct connection without level shifting.

Drivers, Receivers, Transceivers Part Context

The TJA1043 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors. It offers significant improvements over previous generations, such as the TJA1041A, particularly in EMC and ESD performance. The device is AEC-Q100 qualified and designed as a 'dark green' product, being halogen-free and RoHS compliant. It serves as a reliable interface solution for modern automotive electronic control units.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1041A is identified as a predecessor device within the same family. Designers upgrading from earlier generations should verify that the enhanced EMC and diagnostic features of the TJA1043 are compatible with existing system architectures.
