MP6600GR-Z

Overview

The MP6600GR-Z is a bipolar stepper motor driver from Monolithic Power Systems, housed in a 24-QFN (4x4) package. It operates on a supply voltage of 4.5V to 35V and delivers an output current of 1.5A. The device supports full, half, quarter, and eighth-step resolutions for precise motion control. It integrates power MOSFETs with low on-resistance and includes comprehensive protection features such as over-current, over-voltage, under-voltage lockout, and thermal shutdown.

Feature Summary

• Integrates two internal full-bridge drivers with built-in current sampling and regulation, eliminating the need for external sense resistors.
• Features intelligent current regulation and multiple safety protections including over-current, input over-voltage, under-voltage lockout, and thermal shutdown.
• Provides a simple logic interface compatible with both 3.3V and 5V logic inputs without requiring an additional control power supply.

Applications

• Printers
• Office automation equipment
• Security systems

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's latest documentation to confirm environmental compliance status, such as RoHS3 adherence. Ensure that the 24-QFN package dimensions and thermal pad requirements match the target PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact, cost-effective solution for driving bipolar stepper motors. It is suitable for designs needing integrated current regulation and protection within a small footprint. Consider the 1.5A output capability and 35V maximum voltage when matching motor specifications.

Part Context

The MP6600GR-Z belongs to the MP6600 series of integrated bipolar stepper motor drivers. This family is designed to provide space-saving solutions by combining control logic and power stages into a single chip. The GR-Z suffix typically denotes a specific packaging or environmental variant within the standard MP6600 product line.

Replacement Considerations

MP6600GR-P is documented as a parameter-equivalent substitute available from the manufacturer.
