MP6500AGU-P

Overview

The MP6500AGU-P is a bipolar stepper motor driver from Monolithic Power Systems, designed for space-constrained applications. It integrates two full-bridge drivers with internal current sensing and regulation, eliminating the need for external sense resistors. The device supports input voltages from 4.5V to 35V and delivers up to 2.5A output current. It accommodates full-step, half-step, 1/4-step, and 1/8-step modes. Key electrical parameters include a maximum supply voltage of 35V, minimum operating voltage of 4.5V, and an operating temperature range of -40°C to +125°C. The component is housed in a QFN-24 package.

Feature Summary

• Integrates dual full-bridge drivers with built-in current sampling and regulation capabilities
• Supports multiple stepping modes including full, half, quarter, and eighth steps
• Features comprehensive protection mechanisms such as over-current, over-voltage, under-voltage lockout, and thermal shutdown
• Compatible with standard 3.3V and 5V logic interfaces without requiring separate control power

Applications

• Bipolar stepper motor control in industrial automation systems
• Motion control modules for office equipment and printers
• Precision positioning drives in medical devices
• Automotive actuator control applications

Procurement Notes

Verify the specific suffix 'GU' corresponds to the QFN-24 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required thermal performance and pinout specifications for the target PCB layout. Cross-reference the datasheet for any recent updates regarding lead-free soldering profiles and moisture sensitivity levels.

Selection Notes

Select this model when a compact solution with integrated current sensing is required to reduce external component count. The QFN-24 package offers a smaller footprint compared to TSSOP alternatives, suitable for dense layouts. Consider the 2.5A current capability relative to the thermal dissipation limits of the chosen enclosure. Verify that the 4.5V to 35V input range aligns with the system's power supply architecture.

Part Context

This component belongs to the MP6500G series of integrated bipolar stepper motor drivers. The series is characterized by high integration levels, combining control logic, gate drivers, and protection circuits into a single chip. The MP6500AGU-P specifically denotes the automotive-grade or enhanced reliability variant within the broader MP6500 family, utilizing the QFN-24 surface-mount package for optimized thermal and spatial performance.

Replacement Considerations

MP6500GU-P: Same series with identical functional specifications and QFN-24 packaging, differing potentially in manufacturing lot or minor qualification standards.
