MP6539GF

Overview

The MP6539GF is a three-phase brushless DC motor pre-driver from Monolithic Power Systems. It supports a supply voltage range of 8 V to 100 V and delivers a peak output current of 1 A per channel. The device operates with a quiescent current of 700 uA and functions within a temperature range of -40°C to +125°C. Packaged in a QFN-28 format, it integrates six half-bridge drivers for N-channel MOSFETs.

Feature Summary

• Provides dedicated gate drive signals for three-phase BLDC motor applications
• Integrates protection mechanisms against under-voltage lockout and over-current conditions
• Supports non-inverting logic inputs for direct interface with microcontrollers

Applications

• Three-phase brushless DC motor control systems
• Industrial automation and motion control equipment
• Home appliance motor drives

Procurement Notes

Verify the specific suffix (e.g., GF-Z) against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements up to 100 V and validate thermal management for the QFN-28 package during operation.

Selection Notes

Select this component for designs requiring high-voltage tolerance and low standby power consumption. Confirm that the 1 A output current meets load demands and that the QFN-28 footprint aligns with PCB layout constraints. Verify input logic levels match the controlling MCU.

Part Context

This part belongs to the MP6539 series of motor drivers designed for efficient BLDC control. It serves as a pre-driver stage, managing gate signals for external power MOSFETs rather than containing integrated power switches directly.

Replacement Considerations

MP6539GV-P offers identical electrical performance in a QFN-28 package with cut-tape availability options.
