UJA1132HW/FD/5V/0Y

Overview

The UJA1132HW/FD/5V/0Y is a specialized power management IC designed as a system basis chip for automotive applications. It integrates a buck/boost converter providing 5 V at 500 mA and a separate 5 V regulator delivering 100 mA. The device features a high-speed CAN interface supporting data rates up to 1 Mbps and dual LIN interfaces. It includes up to eight high-voltage I/Os (HVIO) and supports optional CAN partial networking functionality, all housed in a 48-lead HTQFP package.

Feature Summary

• Integrates a buck/boost DC-DC converter with dedicated linear regulators for stable power supply rails
• Provides a high-speed CAN transceiver capable of operating at data rates up to 1 Mbps
• Includes dual local interconnect network (LIN) interfaces for flexible communication topologies
• Offers multiple high-voltage input/output pins for direct connection to external sensors and actuators

Applications

• Automotive body control modules requiring integrated power and communication
• Gateway devices utilizing mixed CAN and LIN bus architectures
• Sensor nodes needing isolated power regulation and high-voltage I/O capabilities
• Systems implementing CAN partial networking for reduced power consumption during sleep modes

Procurement Notes

Verify the specific suffix FD/5V/0Y against the manufacturer's current datasheet to confirm pinout compatibility and packaging details. Ensure that the required thermal performance matches the HTQFP-48 package constraints for your specific PCB layout. Cross-reference the ordering part number with official NXP documentation to avoid confusion with similar variants lacking the dual LIN or specific voltage regulator configurations.

Selection Notes

Select this component when a single-chip solution is needed to combine power management with both high-speed CAN and dual LIN communications. It is suitable for designs requiring independent 5 V power rails with different current capacities. Consider the HVIO count if direct interfacing with high-voltage peripherals is necessary without additional level shifters. Evaluate the thermal dissipation requirements of the buck/boost converter under maximum load conditions.

Part Context

This part belongs to NXP's UJA113x family of system basis chips, which are designed to simplify automotive electronic design by integrating essential power and communication functions. These chips typically replace multiple discrete components, reducing board space and complexity. The UJA1132 variant specifically targets applications requiring robust CAN connectivity alongside flexible LIN support and versatile power delivery options.

Replacement Considerations

Check for UJA1132AHW/5F4/0Y or UJA1132HW/5V0 as potential functional equivalents within the same product family. Verify that any substitute maintains the same package type and pinout configuration to ensure mechanical compatibility. Confirm that the alternative part supports the required CAN speed and LIN interface count before finalizing the swap.
