MP6540HGU-Z

Overview

The MP6540HGU-Z is a three-phase power stage designed for brushless DC motor applications, manufactured by Monolithic Power Systems. It operates within a supply voltage range of 5.5 V to 50 V and delivers an output current of 5 A. The device features PWM and ENBL inputs for control. It is housed in a QFN-26 package suitable for surface mount installation. The component supports an operating temperature range from -40°C to +125°C with a power dissipation capability of 5.58 W.

Feature Summary

• Integrates a three-phase power stage for direct BLDC motor drive
• Accepts standard PWM and enable input signals for control
• Supports wide supply voltage operation up to 50 V

Applications

• Brushless DC motor control systems
• Motion control drivers
• Industrial automation actuators

Procurement Notes

Verify the specific suffix Z against official Monolithic Power Systems documentation to confirm RoHS compliance status and lead time requirements. Confirm that the QFN-26 package matches your PCB footprint design. Ensure the 5A output current rating aligns with your thermal management strategy given the 5.58 W power dissipation specification.

Selection Notes

Select this component when a dedicated three-phase power stage is required rather than a full controller IC. Verify that the 5.5 V minimum supply voltage meets your system's low-voltage operational needs. Consider the QFN-26 package size constraints during layout planning. Ensure the 50 V maximum voltage rating exceeds your motor's back-EMF peaks.

Part Context

This part belongs to the MP6540 family of motor drivers from Monolithic Power Systems. It serves as a power stage solution distinct from integrated controllers like the MP6543 or MP6546. The HGU-Z designation indicates the specific package and tape/reel configuration for automated assembly.
