MP6500GU-P

Overview

The MP6500GU-P is a bipolar stepper motor driver from Monolithic Power Systems, housed in a QFN-24 package. It operates within a supply voltage range of 4.5 V to 35 V and delivers an output current of 2.5 A. The device features integrated internal current sampling, eliminating the need for external resistors. It supports full-step, half-step, 1/4-step, and 1/8-step modes. Key protection mechanisms include overcurrent protection (OCP), input overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown.

Feature Summary

• Integrates two internal full-bridge drivers with built-in current regulation and sampling capabilities
• Supports multiple microstepping resolutions including full, half, quarter, and eighth steps
• Provides comprehensive safety protections such as overcurrent, overvoltage, undervoltage lockout, and thermal shutdown

Applications

• Bipolar stepper motor control systems
• Motion control applications requiring precise positioning
• Automotive ignition or actuator drivers

Procurement Notes

Verify the specific suffix GU-P corresponds to the QFN-24 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with 3.3V and 5V logic inputs for interface design. Check for moisture sensitivity classification requirements during storage and handling procedures.

Selection Notes

Select this component for designs requiring a compact solution for bipolar stepper motors without external sense resistors. The QFN-24 package offers space efficiency compared to larger alternatives. Consider the 2.5A current limit and 35V maximum voltage rating against load requirements. Evaluate thermal performance based on the specific PCB layout and heat dissipation capabilities.

Part Context

This part belongs to the MP6500G series of integrated stepper motor drivers. It is designed to replace discrete solutions by combining control logic and power stages into a single monolithic IC. The series emphasizes high integration and reduced board space for motion control applications.

Replacement Considerations

MP6500GF-P is a documented alternative within the same family, utilizing a TSSOP-28 EP package instead of QFN-24. Verify pin-to-pin compatibility and thermal characteristics before substitution.
