UJA1132HW/3V3Y

Overview

The UJA1132HW/3V3Y is a System Basis Chip (SBC) from NXP USA Inc., designed for automotive applications. It integrates a fully automatic SMPS Buck-Boost converter, a High-Speed CAN transceiver, and up to two LIN transceivers. The device operates within a supply voltage range of 2V to 28V and draws a supply current of 2.8mA. It supports an operating temperature range of -40°C to 125°C (TA). The component is housed in a 48-HTQFP (10x10) package with exposed pad and holds AEC-Q100 qualification.

Feature Summary

• Integrates a fully automatic SMPS Buck-Boost converter for efficient power management
• Combines High-Speed CAN transceiver functionality with support for up to two LIN transceivers
• Provides comprehensive protection features including under-voltage and over-temperature monitoring

Applications

• In-vehicle networking systems requiring integrated power and communication
• Automotive electronic control units (ECUs)
• Body control modules utilizing CAN and LIN bus architectures

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm that the recommended substitute, UJA1135AHW/3/0Y, meets all functional requirements for your design. Ensure compatibility with the 48-HTQFP footprint during any transition. Check current availability as stock may be limited or exhausted.

Selection Notes

Select this component when a single-chip solution for power regulation and dual-bus communication is required. The integrated Buck-Boost converter simplifies board layout by handling wide input voltage ranges. Consider the 48-pin HTQFP package constraints for PCB space. Verify that the specific voltage regulator output matches the system's 3.3V requirement implied by the suffix.

Part Context

This SBC belongs to the UJA113x series, which are specialized PMICs for automotive networking. The series typically combines power conversion with transceiver capabilities to reduce component count. The UJA1132 variant specifically focuses on integrating HS-CAN and dual-LIN interfaces alongside the power stage, targeting complex body electronics applications.

Replacement Considerations

The manufacturer recommends UJA1135AHW/3/0Y as a substitute. Verify pinout compatibility and electrical parameter alignment before substitution.
