MP6530GF-P

Overview

The MP6530GF-P is a three-phase brushless DC motor pre-driver from Monolithic Power Systems. It operates within a supply voltage range of 5V to 60V and delivers an output current of 1A per phase. The device features a quiescent operating current of 950 uA and functions at a working frequency of 110 kHz. It supports power dissipation up to 3.9W and operates across a temperature range of -40°C to +125°C. The component is housed in a TSSOP-28 package with exposed pad for thermal management.

Feature Summary

• Supports 100% duty cycle operation via internal trickle charge circuit maintaining bootstrap gate drive voltage
• Includes programmable overcurrent protection, adjustable dead-time control, undervoltage lockout, and overtemperature protection
• Features low-power sleep mode suitable for battery-powered applications
• Provides fault indication output for system monitoring

Applications

• Brushless DC motor drives
• General purpose motor control systems
• Battery-powered equipment requiring low standby current

Procurement Notes

Verify the specific suffix GF against official MPS documentation to confirm the TSSOP-28EP package variant. Ensure compatibility with external N-channel MOSFETs rated for the target voltage. Confirm thermal requirements align with the 3.9W dissipation capability in the selected enclosure. Cross-reference pinouts with the datasheet before PCB layout finalization.

Selection Notes

Select this component for applications requiring wide input voltage support up to 60V. Consider the TSSOP-28EP package for improved thermal performance compared to standard packages. Evaluate the need for external MOSFETs as this is a pre-driver. Check if the 1A output current meets the load requirements. Verify environmental ratings for high-temperature operation up to 125°C.

Part Context

The MP6530 series comprises three-phase BLDC motor pre-drivers designed to drive six N-channel power MOSFETs arranged in three half-bridges. This family includes variants like MP6530GR-P and MP6530GF-Z, differing primarily in packaging options such as QFN-28 and TSSOP-28EP. All variants share core electrical characteristics including voltage range and protection features.
