MP6508GR-Z

Overview

The MP6508GR-Z is a bipolar stepper motor driver from Monolithic Power Systems, featuring integrated power MOSFETs in a full-bridge configuration. It operates within a supply voltage range of 2.7V to 18V and delivers an output current of 1.2A. The device consumes 1.6mA of operating supply current and supports a maximum power dissipation of 2.8W. It functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a TSSOP-16 surface-mount package.

Feature Summary

• Integrates four half-bridges with internal power MOSFETs for compact design
• Supports PWM interface for precise motor control
• Includes over-temperature shutdown and under-voltage lockout protection

Applications

• Bipolar stepper motor control systems
• General-purpose motion control applications
• Automated machinery drive circuits

Procurement Notes

Verify the specific suffix GR against official MPS documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the selected variant aligns with your thermal management requirements and PCB layout constraints. Cross-reference the datasheet for any updates on environmental compliance or lead-free status before finalizing procurement orders.

Selection Notes

Select this component when a fully integrated solution for bipolar stepper motors is required without external discrete drivers. The 1.2A output capability suits moderate load applications. Consider the TSSOP-16 package for space-constrained designs. Verify that the 18V maximum supply voltage meets system power rail specifications.
