MP6500GF-Z

Overview

The MP6500GF-Z is a bipolar stepper motor driver from Monolithic Power Systems, housed in a 28-TSSOP-EP package. It operates on a supply voltage range of 4.5V to 35V and delivers an output current of 2.5A. The device supports step resolutions including full, half, quarter, and eighth steps. Key electrical parameters include a power dissipation of 3.9W and a quiescent supply current of 1.5mA. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• Integrates internal current sampling and regulation, eliminating the need for external sense resistors.
• Features low on-resistance high-side (170mΩ) and low-side (150mΩ) power MOSFETs.
• Includes comprehensive protection mechanisms such as overcurrent protection, input overvoltage protection, undervoltage lockout, and thermal shutdown.
• Provides a fault indication output pin for status monitoring.

Applications

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

Procurement Notes

Verify the specific suffix 'GF' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the 28-TSSOP-EP thermal pad connection requirements are met during assembly to maintain the specified 3.9W power dissipation capability. Confirm RoHS compliance status with the latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is required without external current sensing resistors. The integrated logic interface compatible with 3.3V and 5V inputs simplifies controller interfacing. Consider the 28-TSSOP-EP package for superior thermal performance compared to smaller footprints if higher continuous current or elevated ambient temperatures are anticipated in the design.

Part Context

This part belongs to the MP6500 series of integrated bipolar stepper motor drivers. It combines control logic, current regulation, and power stages into a single monolithic IC. The GF variant specifically denotes the TSSOP-28 package option within the broader product family designed for space-constrained applications requiring high integration.
