MC33907AE

Overview

The MC33907AE is a System Basis Chip (SBC) from NXP Semiconductors designed for automotive applications. It integrates power management and communication interfaces in an LQFP-48EP package. The device supports an input voltage range of 2.7 V to 40 V. It features a DC/DC switching regulator with an output current capability of up to 800 mA, suitable for MCU core supply. The operating temperature range spans from -40 °C to +125 °C. The chip includes integrated High-Speed CAN and LIN transceivers compliant with ISO11898-2/-5 and LIN 2.2 standards.

Feature Summary

• Integrates a flexible DC/DC pre-regulator supporting Buck or Buck-Boost topologies for efficient energy management.
• Includes enhanced safety features with fail-safe outputs and secured SPI interface for functional safety compliance.
• Features ultra-low-power modes with multiple wake-up sources including CAN, LIN, and I/Os.

Applications

• Electric Power Steering
• Engine Management
• Battery Management

Procurement Notes

Verify the specific suffix 'AE' against the official datasheet to confirm pinout and feature set variations. Ensure compatibility with the target MCU's SPI interface requirements. Check for AEC-Q100 qualification status if required by the application. Confirm packaging details such as tray quantity and moisture sensitivity level prior to ordering.

Selection Notes

Select this component when a combined power management and communication solution is needed for safety-critical automotive systems. It is suitable for designs requiring ASIL D support and integrated CAN/LIN physical layers. Consider the 800 mA DC/DC limit for core power needs. Evaluate the need for Buck-Boost topology if input voltage fluctuates significantly during cranking.

Part Context

The MC33907AE belongs to the MC33907/MC33908 family of SmartMOS devices. These chips are designed for multi-output power management in automotive markets. The MC33907 typically offers lower DC/DC current compared to the MC33908. This series simplifies system design by integrating regulators, transceivers, and safety logic into a single package.

Replacement Considerations

MC33908AE serves as a complementary part with higher DC/DC output current capabilities. Verify pin-to-pin compatibility and electrical parameter differences before substitution. Consult the official replacement guide for specific feature distinctions between the MC33907 and MC33908 variants.
