UJA1131HW/5V0,518

Overview

The UJA1131HW/5V0,518 is a System Basis Chip (SBC) integrating an automatic SMPS Buck-Boost converter, High-Speed CAN transceiver, and dual LIN transceivers. It operates on a supply voltage of 2V to 28V with a typical supply current of 2.8mA. The device supports up to 8 HVIO pins and optional CAN Partial Networking. Designed for automotive applications, it functions within a temperature range of -40°C to 125°C TA. The component is housed in a 48-HTQFP (10x10) package with exposed pad.

Feature Summary

• Integrates fully automatic SMPS Buck-Boost converter for efficient power management
• Combines High-Speed CAN transceiver with dual LIN transceiver capabilities
• Supports up to 8 general-purpose I/O pins with high voltage tolerance
• Complies with AEC-Q100 automotive qualification standards

Applications

• In-vehicle networking systems requiring integrated power and communication
• Automotive electronic control units (ECUs) utilizing HS-CAN and LIN buses
• Battery-powered automotive modules operating at low supply voltages

Procurement Notes

This component is officially marked as obsolete and no longer manufactured by NXP USA Inc. Verification of availability should focus on distributor surplus stock or authorized replacement channels. Ensure that any sourced units match the original 48-HTQFP package specifications and AEC-Q100 automotive grade requirements. Cross-reference part numbers carefully to confirm functional equivalence before procurement.

Selection Notes

Select this SBC for designs requiring combined power regulation and multi-bus communication in a single package. The integrated Buck-Boost converter allows operation across wide battery voltage ranges. Consider the 48-pin HTQFP footprint for PCB layout constraints. Verify compatibility with existing CAN and LIN network architectures. Note that the part status is obsolete; alternative sourcing strategies must be implemented for production continuity.

Part Context

The UJA1131HW/5V0,518 belongs to the UJA113x family of System Basis Chips from NXP Semiconductors. This series targets automotive networking applications by combining power management with transceiver functions. The HW variant specifically denotes the Buck-Boost topology and HTQFP packaging. It serves as a central node controller for vehicles requiring robust CAN and LIN connectivity alongside stable power distribution.

Replacement Considerations

NXP recommends UJA1131AHW/5/0Y as the manufacturer-recommended substitute. Both parts share the same functional integration of Buck-Boost converter, HS-CAN, and dual LIN transceivers. Verify pinout compatibility and software configuration settings when transitioning to the replacement part number.
