MP6500AGU-Z

Overview

The MP6500AGU-Z is a bipolar stepper motor driver from Monolithic Power Systems, designed for applications requiring integrated control and power stages. It operates within a supply voltage range of 4.5 V to 35 V and delivers an output current of up to 2.5 A. The device features internal current sensing and regulation, eliminating the need for external sense resistors. It supports full, half, quarter, and eighth-step modes. The component is housed in a QFN-24 (5mm x 5mm) package suitable for surface-mount installation.

Feature Summary

• Integrates two internal full-bridge drivers with built-in current sampling and regulation capabilities
• Supports multiple stepping resolutions including full, half, quarter, and eighth-step modes
• Includes comprehensive protection mechanisms such as over-current, over-voltage, under-voltage lockout, and over-temperature shutdown

Applications

• Printer mechanisms
• Vending machines
• Security systems

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status according to manufacturer declarations. Confirm the QFN-24 package dimensions match the PCB footprint design. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with existing design specifications.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is required without external current sensing resistors. It is suitable for designs needing integrated fault protection and multiple microstepping options. Consider the thermal performance of the QFN-24 package relative to the expected load current and ambient temperature conditions.

Part Context

This part belongs to the MP6500 series of integrated stepper motor drivers. It shares functional similarities with variants like the MP6500GU-P but differs in packaging and compliance attributes. The series is characterized by high integration, reducing bill-of-materials count and board space requirements for motion control applications.

Replacement Considerations

MP6500GU-P is listed as a parameter-equivalent alternative within the same product family.
