MC33907LAE

Overview

The MC33907LAE is a Power System Basis Chip from NXP Semiconductors designed for automotive applications. It integrates a high-speed CAN transceiver with multiple voltage regulators, including buck and boost converters. The device operates within an input voltage range of 2.7 V to 40 V and supports AEC-Q100 qualification. Key electrical parameters include an output current capability of up to 800 mA for specific LDO outputs and a core supply current of approximately 13 mA. It is housed in a 48-lead LQFP-EP package (7x7 mm) suitable for surface mount installation.

Feature Summary

• Integrates a high-speed CAN transceiver with the power management system basis chip functionality
• Includes dedicated buck and boost converters alongside low-dropout regulators for flexible power distribution
• Designed for robust automotive environments with extended temperature ranges and high reliability standards

Applications

• Electrical Power Steering systems
• Automotive body control modules
• General power system basis chip implementations in vehicles

Procurement Notes

Verify that the specific suffix 'LAE' corresponds to the required tape-and-reel or tray packaging configuration as specified in the official ordering information. Confirm that the component meets the AEC-Q100 grade requirements for your target automotive application. Ensure compatibility with the 48-LQFP-EP thermal pad soldering process during assembly planning.

Selection Notes

Select this component when a combined solution for power regulation and high-speed CAN communication is required. It is suitable for designs needing integrated buck/boost capabilities rather than just linear regulation. Consider the 48-pin footprint constraints and the need for external components for the switching regulators when finalizing the schematic design.

Part Context

The MC33907 belongs to NXP's family of Power System Basis Chips, which integrate PMIC functions with communication interfaces. This series targets automotive electronics requiring high integration and safety features. The 'LAE' variant specifically denotes the package type and internal configuration distinct from other suffixes like 'NAE'.
