Datasheet
Automotive LIN Bus Transceiver IC with Low Power Sleep Mode and EMI Optimisation
The TJA1021T/20/CM,118 is a reliable LIN bus transceiver designed to interface a microcontrollers LIN protocol controller with the physical LIN network. Developed by NXP Semiconductors, this device is optimised for in-vehicle sub-network communication, supporting baud rates from 1 kBd up to 20 kBd.
Compliant with LIN 2.x standards, SAE J2602, and ISO 17987-4, the TJA1021 ensures robust and efficient communication in automotive environments. It features optimised slew rate control and waveform shaping to minimise electromagnetic emissions (EME), ensuring stable operation in noise-sensitive systems. With ultra-low power consumption in sleep mode and reduced current during fault conditions, this IC is ideal for automotive body electronics, sensor networks, and actuator control systems.
