SJA1124AHG/0Z

Drivers, Receivers, Transceivers Overview

The SJA1124AHG/0Z is a quad Local Interconnect Network (LIN) commander channel device from NXP Semiconductors. It integrates four LIN commander controllers and transceivers with commander termination, compliant with LIN 2.0 through 2.2A, ISO 17987-4:2016, and SAE J2602-1 standards. The device operates at baud rates up to 20 kBd and interfaces with microcontrollers via a flexible Serial Peripheral Interface (SPI). It supports low power consumption with wake-up capabilities via SPI or LIN pins. The component is housed in a DHVQFN24 package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent LIN commander channels with built-in controller and transceiver functions
• Features an SPI interface for configuration, control, diagnosis, and data transfer with variable length support
• Includes internal LIN commander termination consisting of a diode and pull-up resistor
• Supports synchronous LIN frame transmission across multiple devices via the TMF pin

Drivers, Receivers, Transceivers Applications

• Automotive subnetworks requiring multiple LIN commander channels
• In-vehicle electronic control units (ECUs) connecting to LIN bus networks
• Applications needing reduced MCU pin count through SPI-to-LIN bridging

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'HG/0Z' against the manufacturer's current ordering information to confirm availability and exact package specifications. Ensure compatibility with the required automotive environmental standards and voltage levels before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require multiple LIN channels managed by a single integrated device. It is suitable for applications aiming to minimize bill of materials by integrating termination resistors and reducing the number of microcontroller I/O pins needed for LIN communication.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SJA1124 family of quad LIN commander transceivers. It is designed to replace discrete solutions involving separate transceivers, controllers, and termination components, thereby simplifying PCB layout and reducing overall system complexity in automotive environments.

Drivers, Receivers, Transceivers Replacement Considerations

The SJA1124BHG/0Z is a variant within the same family featuring fixed commander termination. Verify functional differences regarding termination configurability if substituting between A and B variants.
