UJA1079ATW/5/2Z

Overview

The UJA1079ATW/5/2Z is an automotive-grade LIN core System Basis Chip (SBC) from NXP Semiconductors. It integrates a LIN transceiver, voltage regulators, and protection circuits to replace discrete components in Electronic Control Units (ECUs). The device supports supply voltages between 4.5V and 28V with a quiescent current of 75µA. It is qualified under AEC-Q100 standards for reliability in harsh automotive environments.

Feature Summary

• Integrates LIN transceiver and power management functions to simplify ECU design
• Supports automotive networking applications for controlling power and sensor peripherals
• Replaces basic discrete components commonly found in electronic control units

Applications

• Automotive Electronic Control Units (ECUs)
• LIN bus networking applications
• Power and sensor peripheral control systems

Procurement Notes

Verify the specific suffix '5/2Z' against official NXP documentation to confirm package type and tape/reel specifications. Ensure the component meets AEC-Q100 qualification requirements for your target automotive application. Cross-reference ordering information with authorized distributors to avoid counterfeit parts.

Selection Notes

Select this SBC for applications requiring integrated LIN communication and power regulation. Consider the HTSSOP-32 package constraints and the 4.5V to 28V input range. Evaluate thermal performance and pin compatibility if replacing existing discrete solutions or older SBC models in the design.

Part Context

This component belongs to the UJA series of System Basis Chips designed for automotive use. It consolidates multiple functions into a single IC, reducing board space and complexity compared to traditional discrete implementations. The series is tailored for robust operation in vehicle electrical systems.

Replacement Considerations

Check pin-to-pin compatibility with legacy SBCs. Verify that the integrated regulator outputs match the load requirements previously handled by discrete regulators. Confirm LIN protocol version support aligns with the network architecture.
