MPQ6600LGRE-AEC1-P

Overview

The MPQ6600LGRE-AEC1-P is an automotive-grade stepper motor driver from Monolithic Power Systems. It supports a supply voltage range of 4.5 V to 35 V with a typical operating voltage of 24 V. The device delivers a continuous output current of 1.5 A across four outputs. It features a low quiescent current of 2.5 uA and dissipates up to 2.9 W of power. Designed for harsh environments, it operates between -40°C and +125°C. The component is housed in a QFN-24 surface-mount package and holds AEC-Q100 qualification.

Feature Summary

• Integrated internal current sensing mechanism for precise control
• Automotive reliability certified under AEC-Q100 standards
• Low standby power consumption suitable for battery applications

Applications

• Automotive seat adjustment systems
• Vehicle mirror positioning actuators
• Steering column control mechanisms

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm that the specific revision matches the design requirements. Check official manufacturer documentation for updated lifecycle status and recommended landing pad patterns before finalizing procurement.

Selection Notes

Select this driver for applications requiring integrated current sensing and automotive certification. Compare against non-automotive equivalents like the MP6600GR-P if environmental ratings are not required. Ensure the thermal performance of the QFN-24 package meets the system's heat dissipation needs.

Part Context

This component belongs to the MPQ6600L-AEC1 series, which provides specialized solutions for motion control in vehicles. It complements other MPS power management ICs by handling actuator drive functions while maintaining strict automotive quality standards.

Replacement Considerations

The MPQ6600LGRE-AEC1-Z serves as a reel-pack alternative within the same product family.
