MC33907AER2

Overview

The MC33907AER2 is a System Basis Chip (SBC) from NXP Semiconductors, designed for automotive applications. It integrates power management and communication interfaces in a 48-lead LQFP-EP package. Key electrical parameters include an input voltage range of 2.7 V to 40 V. The device features a DC/DC switching regulator capable of delivering up to 1.5 A for MCU core supply, with output voltages adjustable from 1.2 V to 3.3 V. It also includes linear regulators providing 5.0 V or 3.3 V outputs. The operating temperature range spans from -40 °C to +125 °C.

Feature Summary

• Integrates high-speed CAN and LIN physical interfaces compliant with ISO11898-2/-5 and LIN 2.2 standards.
• Features a flexible DC/DC pre-regulator supporting Buck or Buck-Boost topologies for efficient energy management.
• Includes enhanced safety functions with fail-safe outputs and support for ASIL D functional safety requirements.
• Provides multiple wake-up sources including CAN, LIN, I/Os, and current detection for ultra-low-power modes.

Applications

• Electric Power Steering
• Engine Management Systems
• Battery Management Systems
• Advanced Driver Assistance Systems (ADAS)
• Hybrid Electric Vehicles (HEV)

Procurement Notes

Verify the specific suffix 'R2' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official NXP documentation. Ensure the component meets AEC-Q100 qualification requirements for automotive reliability. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component for designs requiring integrated power regulation and robust communication interfaces in a single package. The 1.5 A DC/DC output supports high-current MCU cores. Consider the ASIL D capability if functional safety certification is mandatory. Evaluate the need for Buck-Boost topology if input voltage fluctuations are significant during cranking events.

Part Context

The MC33907 series belongs to NXP's third-generation System Basis Chips. These devices combine power management units with physical layer transceivers. The family targets complex automotive electronic control units. Integration reduces bill of materials and board space compared to discrete solutions.

Replacement Considerations

MC33908 is a functionally similar variant within the same family. Verify pin compatibility and specific output current ratings before substitution. Consult NXP datasheets for detailed differences between MC33907 and MC33908 models.
