Overview

The TJA1021TK/20/C,118 is a specialized Local Interconnect Network (LIN) transceiver designed to interface between a LIN protocol controller and the physical bus. It is fully compliant with LIN 2.x and SAE J2602 standards, supporting communication speeds up to 20 kBd. This device is engineered for harsh automotive environments with high electromagnetic immunity and very low emissions.

Why Choose This Part

This transceiver offers exceptional energy efficiency with a sleep mode current of only 7 uA and a standby mode of 450 uA. It features integrated protection against battery short circuits, thermal overloads, and high ESD transients up to +/-6 kV. The leadless HVSON8 package is optimized for space-constrained designs and supports Automated Optical Inspection (AOI).

Applications

Automotive Body Control
Ideal for low-speed communication in door modules, seat control, and window lifters where LIN bus is standard.
Sensor and Actuator Networking
Connects simple sensors and actuators to a master controller in vehicle climate control and lighting systems.
K-line Diagnostic Interface
The transceiver is compatible with K-line signaling, allowing it to be used in legacy automotive diagnostic tools.

Getting Started

To evaluate this part, use a microcontroller with a standard UART peripheral connected to the TXD and RXD pins. Ensure the VBAT supply is within the 5.5V to 27V range and add the necessary pull-up resistors for LIN responder configurations if the internal termination is insufficient for your bus load. Consult the NXP application notes for layout recommendations to minimize electromagnetic emissions.
