MC33907NAER2

Overview

The MC33907NAER2 is a System Basis Chip (SBC) from NXP Semiconductors designed for automotive applications. It integrates multiple power management functions with high-speed CAN and LIN transceivers. The device features a buck-boost SMPS pre-regulator and dedicated linear regulators, supporting input voltages from 2.7 V to 40 V. It provides up to 1.5 A output current for the MCU core voltage, adjustable between 1.2 V and 3.3 V. Additional outputs include auxiliary LDOs for sensors and ADC references. The component operates within a temperature range of -40°C to +125°C and is housed in a 48-LQFP-EP package.

Feature Summary

• Integrates a flexible buck-boost or standard buck SMPS pre-regulator for efficient power conversion across wide input voltage ranges.
• Includes enhanced high-speed CAN interface compliant with ISO11898-2 and -5 standards, featuring local and bus fault diagnostics.
• Supports low-power modes with multiple wake-up sources including CAN, LIN, and I/O transitions.
• Provides advanced safety features with fail-safe outputs and support for ASIL D application integrity levels.

Applications

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

Procurement Notes

Verify that the specific suffix 'R2' corresponds to the reel packaging configuration as defined by the manufacturer's ordering information. Confirm that the device meets the required automotive qualification standards, such as AEC-Q100, for your specific application environment. Ensure compatibility with the intended PCB footprint and thermal requirements associated with the LQFP-48 package type before finalizing procurement.

Selection Notes

Select this component when a combined power management and communication solution is required for safety-critical automotive ECUs. It is suitable for designs needing an integrated buck-boost regulator to handle wide input voltage variations typical in vehicle electrical systems. Consider its ASIL D capability if functional safety compliance is mandatory. Evaluate the need for integrated CAN and LIN interfaces to reduce external component count and board space.
