MPQ6531GVE-AEC1-Z

Overview

The MPQ6531GVE-AEC1-Z is a three-phase brushless DC motor pre-driver from Monolithic Power Systems, designed for automotive applications with AEC-Q100 Grade 1 qualification. It operates within a supply voltage range of 5V to 60V and supports junction temperatures from -40°C to +150°C. The device is housed in a QFN-28 surface-mount package and features a power dissipation rating of 3.1W. It serves as a control interface for external high-voltage power stages in motion and ignition systems.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive reliability standards
• Supports wide input voltage range up to 60V
• Integrated protection mechanisms including over-temperature and under-voltage lockout
• Designed for driving three-phase BLDC motor configurations

Applications

• Automotive cooling fan motor control
• Electric power steering (EPS) systems
• Fuel pump drive circuits
• Ignition coil driver interfaces
• General automotive motion control modules

Procurement Notes

Verify component authenticity through authorized MPS distributors or certified partners. Confirm the specific suffix matches the required automotive grade and packaging configuration. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering. Cross-reference the ordering part number with the latest datasheet revision to confirm pinout and electrical specifications match the design intent.

Selection Notes

Select this pre-driver when a dedicated control IC is required to manage external power MOSFETs in high-voltage automotive environments. It is suitable for designs needing robust protection features without integrating high-current power switches. Consider thermal management capabilities given the 3.1W dissipation limit in the QFN-28 package. Evaluate system voltage requirements against the 60V maximum limit.

Part Context

This component belongs to the MPQ6531 series of motor drivers from Monolithic Power Systems. It complements other MPS automotive PMIC solutions by providing specialized pre-driving functionality for brushless DC motors. The series focuses on meeting stringent automotive quality standards while offering flexible integration with external power stages.

Replacement Considerations

Direct substitutes include other MPS AEC-Q100 qualified three-phase pre-drivers such as the MPQ6533 series, though pinouts and voltage ranges may differ. Verify functional compatibility and thermal performance before swapping components. Consult official MPS documentation for cross-reference lists.
