MP6532-GR-P

Overview

The MP6532GR-P is a three-phase brushless DC motor pre-driver from Monolithic Power Systems. It operates within a 5V to 60V supply range and delivers an output current of 800 mA. The device features a low quiescent current of 950 uA and supports an operating temperature range from -40°C to +125°C. It utilizes a QFN-28 package with dimensions of 4mm x 4mm. Key electrical parameters include a maximum power dissipation of 2.9 W and a working frequency of 110 kHz.

Feature Summary

• Integrates a trickle charge circuit to maintain high-side gate drive voltage, enabling 100% duty cycle operation without bootstrap capacitor discharge issues.
• Supports Hall sensor inputs for integrated 120-degree commutation control alongside PWM speed and direction management interfaces.
• Includes programmable overcurrent protection, adjustable dead-time control, undervoltage lockout, and thermal shutdown for robust system safety.

Applications

• Three-phase brushless DC motor drives
• Battery-powered appliance motor control
• Industrial motion control systems

Procurement Notes

Verify the specific suffix GR-P corresponds to the QFN-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected component matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this model for applications requiring wide input voltage support up to 60V and high output current capability. Consider the QFN-28 package for compact designs needing efficient heat dissipation via the exposed pad. Evaluate the need for Hall sensor integration versus back-EMF sensing based on the specific motor control strategy.

Part Context

The MP6532 belongs to the MPS MP653x series of BLDC pre-drivers. It is designed to interface with external N-channel power MOSFETs to drive three half-bridges. The series offers various package options including TSSOP and QFN variants to suit different PCB layout constraints and thermal requirements.

Replacement Considerations

MP6532GR-Z serves as a direct alternative with identical electrical characteristics but differs in packaging configuration. Verify pin compatibility and thermal performance when substituting between QFN and TSSOP footprints.
