MP6504GV-Z

Overview

The MP6504GV-Z is a stepper motor driver from Monolithic Power Systems, designed for bipolar stepper motors. It operates within an input voltage range of 8V to 32V and delivers a maximum output current of 2A. The device integrates two internal full-bridge drivers with low on-resistance MOSFETs (220mΩ high-side, 220mΩ low-side). It supports full-step, half-step, 1/4-step, and 1/8-step microstepping modes. The component functions without a separate logic supply, utilizing a fixed 3.3V reference output. It is housed in a 28-QFN (4mm x 5mm) package with an exposed thermal pad.

Feature Summary

• Integrated microstepping controller supporting full, half, quarter, and eighth step modes
• Built-in adjustable mixed decay ratio for improved motor performance
• Comprehensive protection mechanisms including overcurrent, overvoltage, undervoltage lockout, and overtemperature shutdown
• Direct compatibility with 3.3V and 5V logic interfaces

Applications

• Bipolar stepper motor control systems
• Motion control applications requiring integrated drive and logic
• Devices needing fault indication via dedicated output pin

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official documentation to confirm compliance with RoHS3 standards and environmental declarations. Ensure the ordering quantity aligns with the standard factory packaging configuration of 5,000 units per reel. Confirm that the QFN-28 package dimensions match the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required, eliminating the need for external logic power supplies. It is suitable for designs where space efficiency is critical due to the compact QFN-28 footprint. Consider the 2A current capability and integrated protection features for robust operation in industrial or consumer motion control environments.

Part Context

The MP6504GV-Z belongs to the MP6504 series of stepper motor drivers manufactured by Monolithic Power Systems. This series focuses on integrating control logic and power stages into a single package to simplify system design. The 'GV' designation indicates the specific package type and temperature rating, while 'Z' denotes environmental compliance attributes defined by the manufacturer.

Replacement Considerations

MP6504GV-P is listed as a direct substitute part number by the manufacturer.
