MP6500GF

Overview

The MP6500GF is a bipolar stepper motor driver from Monolithic Power Systems, featuring an integrated translator and current regulator. It supports full, half, quarter, and eighth-step modes with a supply voltage range of 4.5V to 35V and output currents up to 2.5A. The device includes internal current sensing, eliminating the need for external resistors. Protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown.

Feature Summary

• Integrated control logic and power stage for simplified design
• Internal current sampling and regulation without external resistors
• Multiple microstepping resolution options including full to eighth step
• Comprehensive safety protections against overcurrent, overvoltage, and overheating

Applications

• Printer mechanisms
• Office automation equipment
• Industrial motion control systems

Procurement Notes

Verify the specific suffix (e.g., GF-Z or GF-P) to confirm the package type, as the base model number covers multiple physical configurations. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Ensure the ordering quantity matches the manufacturer's standard packaging requirements for the selected variant.

Selection Notes

Select this component for applications requiring a compact solution for bipolar stepper motors. The integrated translator reduces microcontroller load. Consider the thermal performance of the TSSOP-28 EP package for higher current loads compared to smaller packages. Verify that the input voltage range aligns with the system power supply.

Part Context

This part belongs to the MP6500G series of integrated bipolar stepper motor drivers. The series is designed to offer high integration and space-saving solutions. Variants within the series differ primarily in package style, such as QFN-24 or TSSOP-28, while maintaining similar electrical characteristics and functional capabilities.

Replacement Considerations

Check datasheets for pin-to-pin compatibility with existing designs. Verify that alternative drivers support the same microstepping resolutions and current limits. Ensure replacement parts meet the required operating temperature range and voltage specifications.
