TJA1043TKJ

Drivers, Receivers, Transceivers Overview

The TJA1043TKJ 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 complies with ISO 11898-2:2016 and SAE J2284 standards, supporting data rates up to 5 Mbit/s in the CAN FD fast phase. It operates within a VCC supply voltage range of 4.5 V to 5.5 V and supports VIO levels from 2.8 V to 5.5 V. The component features low-power management with Standby and Sleep modes, enhanced EMC/ESD performance, and diagnostic functions including bus short-circuit detection. It is available 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 operating temperature ranges and supply voltage conditions before integration. Cross-reference part numbers with authorized distributors to confirm authenticity and availability status.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring direct interfacing with 3 V or 5 V microcontrollers without additional level shifting logic. Consider the HVSON14 package for applications needing improved Automated Optical Inspection capabilities and enhanced thermal performance. Evaluate the need for specific diagnostic flags and wake-up source recognition features inherent to this third-generation transceiver.

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 first- and second-generation devices like the TJA1041A. The TJA1043T variant uses an SO14 package, while the TJA1043TK variant utilizes the leadless HVSON14 package. The 'J' suffix typically denotes specific packaging or reel configurations.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1041A is a previous generation device with lower EMC and ESD performance. For secure CAN applications, consider the TJA1153. Direct pin-to-pin replacement should be verified against the specific power management and diagnostic requirements of the existing design.
