MP6507GR-Z

Overview

The MP6507GR-Z is a bipolar stepper motor driver from Monolithic Power Systems, featuring an integrated full-bridge architecture with N-channel power MOSFETs. It operates within a supply voltage range of 2.7V to 15V and delivers up to 700mA output current per channel. The device utilizes a 16-pin QFN package (3mm x 3mm) for surface mount installation. Key electrical parameters include a typical operating supply current of 1.1mA and a maximum power dissipation of 2.7W. It supports operation across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates two full-bridge drivers with internal charge pumps for high-side gate drive
• Includes over-temperature shutdown protection with an associated status flag output
• Features under-voltage lockout and programmable current limiting via external sensors
• Offers low quiescent current and microamp-level sleep mode consumption

Applications

• Battery-powered portable devices requiring efficient motor control
• Small form-factor automation systems
• Consumer electronics with integrated motion capabilities

Procurement Notes

Verify the specific suffix GR-Z corresponds to the 16-QFN 3x3mm package when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design reviews account for the thermal performance limits defined in the datasheet for the selected enclosure type.

Selection Notes

Select this component for applications requiring a compact solution for bipolar stepper motors with moderate current demands. Consider the 16-QFN footprint for space-constrained PCB layouts. Evaluate the need for external current sensing resistors if precise limit control is required beyond standard internal protections.

Part Context

This part belongs to the MP6507 series of motor drivers designed by Monolithic Power Systems. The series focuses on providing integrated power stages for small stepper motors, reducing the bill of materials by combining control logic and power MOSFETs into a single IC suitable for various consumer and industrial applications.

Replacement Considerations
