MP6506GQ-P

Overview

The MP6506GQ-P is a bipolar stepper motor driver from Monolithic Power Systems, designed for applications requiring integrated control and power stages. It features built-in dual full-bridge N-channel power MOSFETs capable of delivering up to 500mA output current per channel. The device operates within a wide supply voltage range of 2.7V to 15V and includes an internal charge pump to maintain high-side drive voltages. Key electrical parameters include a low quiescent current of 1.1mA and a standby current of 1µA. It is housed in a thermally enhanced 3mm x 3mm QFN-16 package with an exposed pad for improved heat dissipation.

Feature Summary

• Integrates dual full-bridge drivers with N-channel MOSFETs for complete bipolar stepper motor control
• Includes over-temperature shutdown protection and under-voltage lockout for system reliability
• Features an over-temperature status flag output to indicate thermal protection events
• Utilizes an internal charge pump to ensure consistent high-side gate driving

Applications

• Bipolar stepper motor control in embedded systems
• Precision motion control modules
• Automotive interior actuation systems
• Industrial automation components

Procurement Notes

Verify the specific suffix GQ against the manufacturer's official documentation to confirm pinout compatibility and thermal pad configuration. Ensure that the ordering information matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm feature consistency before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is needed without external discrete power transistors. The integrated design reduces board space and simplifies schematic complexity. Consider the 500mA current limit and 15V maximum voltage rating to ensure they align with the connected motor's electrical requirements and operating environment.
