MP6550GG-Z

Overview

The MP6550GG-Z is a half-bridge motor driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 1.8 V to 22 V and delivers an output current of 2 A. The device features a low quiescent current of 850 uA and supports a switching frequency of 100 kHz. It functions across an extended temperature range from -40°C to +125°C. The component utilizes a 12-VFQFN package with dimensions of 2x2 mm for surface mount installation.

Feature Summary

• Integrates control logic and power MOSFETs in a single compact package
• Supports lower input logic high-level threshold for direct microcontroller interfacing
• Provides PWM interface for precise motor speed and direction control

Applications

• Brushed DC motor control systems
• Unipolar stepper motor drivers
• General purpose motion control applications

Procurement Notes

Verify the specific suffix GG-Z against official datasheets to confirm pinout and thermal pad configuration. Ensure compatibility with the target PCB footprint, specifically the 12-QFN(2x2) outline. Confirm RoHS3 compliance status if required by assembly specifications. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact solution for driving brushed DC or unipolar stepper motors is required. The integrated design reduces external component count compared to discrete solutions. Consider the 2 A continuous current capability and the wide operating voltage range for flexible system design. Evaluate thermal performance requirements given the small QFN package size.
