MP6500LGU-P

Overview

The MP6500LGU-P is a bipolar stepper motor driver from Monolithic Power Systems, designed for compact motion control applications. It operates within a supply voltage range of 4.5V to 35V and delivers an output current of 2.5A. The device integrates two full-bridge drivers with internal current sensing and regulation, eliminating the need for external sense resistors. It supports step resolutions including full, half, quarter, and eighth steps. The component functions reliably across an operating temperature range of -40°C to +125°C and utilizes a QFN-24 package.

Feature Summary

• Integrates internal current sampling and regulation capabilities
• Supports multiple stepping modes from full to eighth step resolution
• Includes comprehensive protection mechanisms such as overcurrent, overvoltage, undervoltage lockout, and thermal shutdown

Applications

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

Procurement Notes

Verify that the specific suffix 'P' corresponds to the required tape and reel packaging configuration rather than cut tape or other variants. Confirm that the QFN-24 footprint matches the target PCB design. Ensure compliance with moisture sensitivity level requirements during storage and soldering processes to maintain component integrity.

Selection Notes

Select this model when internal current sensing is preferred to reduce bill of materials cost by omitting external shunt resistors. Choose the QFN-24 package for space-constrained designs requiring surface mount technology. Consider the 2.5A current capability and 35V voltage limit against specific motor load requirements before finalizing the design.

Part Context

This component belongs to the MP6500L series, which distinguishes itself through integrated latch-off protection features. It shares the core architecture of the MP6500 family but offers enhanced fault handling capabilities. The part serves as a complete solution for driving bipolar stepper motors in embedded systems requiring precise position control.

Replacement Considerations

MP6500LGU-Z is a confirmed parameter-equivalent substitute available from the manufacturer.
