TJA1124AHG/0Z

Drivers, Receivers, Transceivers Overview

The TJA1124AHG/0Z is a quad LIN commander transceiver from NXP Semiconductors, designed to interface between a LIN commander protocol controller and the physical bus. It integrates four LIN transceivers with LIN commander termination (diode and pull-up resistor) compliant with LIN 2.x standards. The device supports baud rates up to 20 kBd and operates within a battery supply voltage range of 5 V to 28 V and a VIO range of 2.97 V to 5.5 V. It features very low current consumption in Low Power mode, wake-up capabilities via SLP or LIN pins, and includes protection against overtemperature, undervoltage, and ESD events.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four LIN commander channels with optimized bus signal shaping for electromagnetic emission minimization
• Supports Low Power mode with remote wake-up detection on LIN pins and local wake-up via the SLP pin
• Provides passive behavior in unpowered state and protects against automotive transient voltages and short circuits
• Includes thermal protection, TXD dominant timeout, and LIN dominant timeout functions

Drivers, Receivers, Transceivers Applications

• In-vehicle subnetworks using baud rates up to 20 kBd
• Automotive LIN commander applications requiring multiple LIN channels
• Systems requiring compliance with ISO 17987-4:2016 and SAE J2602-1 standards

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the DHVQFN24 requires proper soldering techniques. Ensure compatibility with system voltage levels and communication protocols before integration.

Drivers, Receivers, Transceivers Selection Notes

Select the TJA1124A variant specifically for its integrated LIN commander termination consisting of a diode and a pull-up resistor within the specified resistance range. Consider the DHVQFN24 package dimensions for PCB layout constraints and ensure adequate thermal management due to the exposed pad requirement.

Drivers, Receivers, Transceivers Part Context

The TJA1124 series comprises three variants: A, B, and C. The TJA1124A variant features a specific LIN commander termination configuration. This part belongs to the broader family of LIN transceivers designed for automotive networks, offering enhanced EMC performance and low power consumption compared to earlier generations.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other TJA1124 variants such as TJA1124BHG/0Z and TJA1124CHG/0Z, which share the same package and general functionality but differ in LIN commander termination characteristics.
