MP6530GR-P

Overview

The MP6530GR-P is a three-phase brushless DC motor pre-driver from Monolithic Power Systems. It operates within a wide supply voltage range of 5V to 60V and drives up to six N-channel power MOSFETs arranged in three half-bridges. The device features an internal trickle charge circuit for bootstrap capacitors, enabling 100% duty cycle operation. Key electrical parameters include a quiescent current of 950 uA and support for external MOSFET overcurrent protection with adjustable dead-time control. It is housed in a QFN-28 package.

Feature Summary

• Internal trickle charge circuit maintains bootstrap gate drive voltage for continuous 100% duty cycle operation
• Adjustable dead-time control prevents shoot-through between high-side and low-side switches
• Comprehensive protection suite includes programmable overcurrent protection, under-voltage lockout, and over-temperature protection
• Low-power sleep mode designed for battery-powered applications

Applications

• Brushless DC motor drives in consumer electronics
• Industrial automation and motion control systems
• Battery-operated appliances requiring efficient power management

Procurement Notes

Verify the specific suffix GR-P against the official MPS datasheet to confirm the QFN-28 packaging and tape-and-reel configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Cross-reference the component marking code with manufacturer documentation to authenticate the source and prevent counterfeit risks during acquisition.

Selection Notes

Select this pre-driver when designing three-phase BLDC systems requiring a 60V input capability and integrated bootstrap charging. It is suitable for applications needing precise dead-time adjustment and robust fault protection mechanisms. Consider the QFN-28 package for compact designs requiring effective heat dissipation through the exposed pad.

Part Context

The MP6530GR-P belongs to the MP6530 family of pre-drivers, which are specialized ICs for controlling external power stages in motor applications. This series focuses on providing reliable gate driving signals while managing safety limits. The GR-P variant specifically denotes the QFN-28 surface-mount package option within the broader product line.
