MP6631HGL-0000-P

Overview

The MP6631HGL-0000-P is a three-phase brushless DC (BLDC) motor driver manufactured by Monolithic Power Systems. It features integrated power MOSFETs and supports a maximum input voltage of 35V with a peak phase current capability of 3A. The device is designed for sensorless control applications, supporting either a single external Hall-effect sensor or triple external sensors for commutation. It operates within a temperature range of -40°C to +125°C and is housed in a 26-QFN (3x4) package.

Feature Summary

• Integrates high-side and low-side power MOSFETs for compact design
• Supports sensorless BLDC operation or external Hall-effect sensor inputs
• Provides robust thermal performance across extended industrial temperature ranges

Applications

• Three-phase BLDC motor control systems
• Industrial automation actuators
• Consumer appliance motor drives

Procurement Notes

Verify the specific suffix 'HGL' against official MPS documentation to confirm pinout and thermal pad configuration. Ensure the selected variant matches the required package dimensions for PCB layout compatibility. Cross-reference the datasheet revision date to confirm support for latest firmware or hardware errata updates before finalizing procurement.

Selection Notes

Select this component when a monolithic solution for three-phase BLDC motors is required with integrated power stages. Consider the 3A peak current rating relative to the motor's stall requirements. Evaluate the need for external Hall sensors versus pure sensorless algorithms based on application startup torque needs. Verify that the 35V input range aligns with the system power supply specifications.

Part Context

This part belongs to the MP6631 family of three-phase BLDC drivers from Monolithic Power Systems. It shares core architecture with variants like MP6631GL but differs in packaging and specific electrical characteristics defined by the HGL suffix. The family targets efficient motor control solutions requiring integrated power management and precise commutation logic.

Replacement Considerations

MP6631GL-0000-Z is listed as a parametric equivalent in distributor databases. Verify pin-to-pin compatibility and electrical parameter alignment with official MPS substitution guides before replacement.
