MP6651GD-0000-P

Overview

The MP6651GD-0000-P is a single-phase brushless DC (BLDC) motor driver manufactured by Monolithic Power Systems. It integrates power MOSFETs and supports an output current of 2A. The device operates within a supply voltage range of 3.3V to 18V and features an integrated Hall sensor interface. It functions at a working frequency of 27 kHz with a maximum power dissipation of 1.3 W. The component is rated for junction temperatures between -40°C and +125°C. It utilizes a 10-QFN (2x3) surface-mount package.

Feature Summary

• Integrates bipolar motor driver power MOSFETs with PWM control interface
• Supports single-phase BLDC motor applications with full integration of control and power stages
• Includes integrated Hall sensor functionality for commutation

Applications

• Fan motor drivers
• Single-phase BLDC motor control systems

Procurement Notes

Verify the specific suffix GD against other available variants such as GSS or GJL, as package types differ significantly between SOIC-8, TSOT-23-6-L, and QFN configurations. Confirm that the 10-QFN (2x3) footprint matches your PCB layout requirements. Ensure compatibility with the 3.3V to 18V supply range and check for RoHS compliance status in the latest datasheet before finalizing procurement.

Selection Notes

Select this component when a compact 10-QFN package is required for single-phase BLDC applications. It is suitable for designs needing integrated Hall sensing and up to 2A output current. Compare against the MP6651GSS variant if an SOIC-8 package is preferred, or the MP6650 series if different current ratings are needed. Ensure the thermal performance of the QFN package meets the system's heat dissipation needs given the 1.3W power dissipation rating.

Part Context

This part belongs to the MP6651 series of motor controllers and drivers from Monolithic Power Systems. The series includes variants like MP6651GSS and MP6651GD, which share similar functional capabilities but differ in packaging. The MP6651 series is designed for efficient control of single-phase BLDC motors, integrating necessary power stages and control logic into a small form factor.

Replacement Considerations

The MP6651GSS-0000-P is a direct functional alternative housed in an 8-SOIC package. For lower current requirements, the MP6650 series may be considered, though it uses a TSOT-23-6-L package. Verify pinout compatibility and thermal characteristics when substituting these parts.
