MC33907NAE

Overview

The MC33907NAE is a specialized Power System Basis Chip (SBC) from NXP Semiconductors designed for automotive applications. It integrates multiple voltage regulators, including a high-current Vcore buck converter and LDOs, alongside a High-Speed CAN transceiver. The device operates within an input voltage range of 2.7 V to 40 V and supports output voltages from 1.2 V to 3.3 V. It features an 800 mA output current capability and functions reliably across a temperature range of -40°C to +125°C. Packaged in a 48-pin LQFP-EP surface-mount format, it serves as a central power management unit.

Feature Summary

• Integrates a multi-output voltage regulator system with dedicated Vcore and auxiliary LDO capabilities
• Includes a built-in High-Speed CAN transceiver for robust automotive communication
• Designed with functional safety mechanisms suitable for critical automotive electronic systems

Applications

• Electrical Power Steering systems
• Automotive Engine Control Units
• Body Control Modules
• General automotive power distribution networks

Procurement Notes

Verify the specific suffix 'NAE' against the official NXP datasheet to confirm package type and tape-and-reel or tray configuration. Ensure compatibility with AEC-Q100 qualification standards required for automotive deployment. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a combined power regulation and CAN communication solution is required for automotive ECUs. It is appropriate for designs needing a single-chip integration of Vcore supply and bus interface. Consider the 48-pin LQFP footprint for PCB layout constraints. Evaluate thermal performance requirements given the integrated buck converter and operating temperature range.

Part Context

The MC33907 belongs to NXP's Power System Basis Chip family, which consolidates power management and communication interfaces into a single package. This series targets automotive electronics requiring high reliability and space efficiency. The MC33907NAE variant specifically denotes the standard commercial/automotive grade version with the associated packaging and pinout configuration defined by the manufacturer.

Replacement Considerations

Consult the NXP product selection guide for direct cross-references such as MC33907LAE or MC33907AER2. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Review any engineering change notices regarding package updates or feature modifications in newer revisions.
