MP6518GF-Z

Overview

The MP6518GF-Z is a bipolar stepper motor driver from Monolithic Power Systems, designed for applications requiring integrated control and power stages. It operates within an input voltage range of 8V to 35V and delivers a continuous output current of 1.5A. The device features four half-bridge outputs and supports multiple step resolutions including full, half, quarter, and eighth steps. It functions reliably across a junction temperature range of -40°C to +125°C and is housed in a 28-TSSOP-EP package with exposed pad for thermal management.

Feature Summary

• Integrates logic control and power MOSFET stages for simplified design
• Supports variable step resolutions including full, half, quarter, and eighth steps
• Features serial interface for configuration and control

Applications

• Bipolar stepper motor control systems
• General purpose motion control applications
• Industrial automation equipment

Procurement Notes

Verify the specific suffix GF-Z against official MPS documentation to confirm pinout and packaging details. Confirm RoHS compliance status through manufacturer declarations. Check moisture sensitivity level requirements for storage and handling procedures prior to assembly.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is required with integrated power switching. Ensure the load current does not exceed 1.5A and the supply voltage remains within the 8V to 35V range. Consider thermal dissipation capabilities given the 28-TSSOP-EP package constraints for high-temperature environments.
