MP6507GQ-Z

Overview

The MP6507GQ-Z is a fully integrated bipolar stepper motor driver manufactured by Monolithic Power Systems. It features four half-bridge outputs with a peak output current of 700mA per channel. The device operates on a supply voltage range of 2.7V to 15V and supports parallel interfaces for control signals. It utilizes power MOSFET technology within a 16-VFQFN package measuring 3mm x 3mm with an exposed thermal pad. The component supports step resolutions of 1 and 1/2, and functions reliably across a junction 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 low quiescent current operation with a dedicated low-power sleep mode
• Provides under-voltage lockout and current limiting capabilities for system safety

Applications

• Battery-powered portable devices requiring efficient motor control
• Bipolar stepper motor actuation in compact electronics
• Brushed DC motor driving applications
• Automotive interior systems such as seat adjustment or mirror positioning

Procurement Notes

Verify the specific suffix GQ-Z corresponds to the 16-QFN 3x3mm package variant when sourcing. Confirm RoHS3 compliance status aligns with regional regulatory requirements. Check manufacturer documentation for lead time variations, as standard delivery periods may extend significantly. Ensure ESD handling protocols are followed during assembly due to the small form factor and exposed pad design.

Selection Notes

Select this component for designs requiring a compact solution for bipolar stepper motors with moderate current demands. The integrated power stage eliminates external discrete MOSFETs, reducing board space. Consider the thermal performance of the QFN package for high-duty cycle operations. Verify that the 2.7V minimum supply voltage meets the system's battery discharge curve requirements.

Part Context

This part belongs to the MP6507 family of motor drivers from Monolithic Power Systems. The family includes variants with different packaging options such as TSSOP-EP and larger QFN footprints. The GQ-Z suffix specifically denotes the smaller 3x3mm QFN package configuration. These drivers are designed to simplify motor control circuitry by combining logic and power stages into a single IC.
