MP6519GQ-Z

Overview

The MP6519GQ-Z is a high-current H-bridge motor driver manufactured by Monolithic Power Systems. It integrates power MOSFETs and control logic to drive brushed DC motors with a continuous output current of 5A. The device operates within a supply voltage range of 2.5V to 28V, supporting low-voltage applications. It features a PWM interface for speed and direction control. Packaged in a compact 19-QFN (3x3mm) footprint, it supports junction temperatures from -40°C to +125°C.

Feature Summary

• Integrates dual half-bridge outputs with internal power MOSFETs for efficient brushed DC motor driving
• Supports Pulse Width Modulation (PWM) input signals for precise speed and direction regulation
• Operates across an extended industrial temperature range suitable for demanding environments

Applications

• Brushed DC motor control in portable electronics
• Motor drivers in automotive subsystems
• Actuator control in industrial automation equipment

Procurement Notes

Verify the specific suffix 'GQ' against the manufacturer's latest datasheet to confirm package dimensions and pinout compatibility. Ensure the ordering code matches the required tape-and-reel or cut-tape configuration. Cross-reference the RoHS compliance status with current environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution for 5A brushed DC motors is required. It is suitable for designs needing a small form factor due to the QFN package. Consider thermal management requirements as the device dissipates heat proportional to load current and on-resistance. Verify that the system voltage remains within the 2.5V to 28V operational window.

Part Context

This part belongs to the MP6519 family of motor drivers from Monolithic Power Systems. It is designed to replace discrete MOSFET solutions, reducing board space and simplifying design complexity. The series focuses on providing integrated protection features and high efficiency for mobile and automotive applications requiring reliable motor actuation.

Replacement Considerations

Check for direct substitutes such as the MP6519GF-Z if a different package type like TSSOP is preferred. Verify pin-to-pin compatibility and electrical specifications before swapping packages. Consult the manufacturer's selection guide for alternative drivers with similar current ratings but different voltage ranges.
