MP6613GV-Z

Overview

The MP6613GV-Z is a fully integrated H-bridge motor driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4.5 V to 45 V and delivers an output current of 5 A. The device supports both brushed DC motors and bipolar stepper motors, featuring two half-bridge outputs. It utilizes a 28-QFN (4x5 mm) package with an exposed pad for thermal management. The component functions across a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates control logic and power MOSFETs into a single compact solution
• Supports bidirectional drive for brushed DC motors and step control for bipolar stepper motors
• Includes built-in protection mechanisms against over-current and thermal overload

Applications

• Brushed DC motor control in industrial automation systems
• Bipolar stepper motor driving in office equipment
• Valve actuation in automotive applications

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance during procurement. Confirm the 28-QFN footprint matches the target PCB layout. Ensure adequate thermal relief is designed on the board to handle the exposed pad requirements for optimal heat dissipation under full load conditions.

Selection Notes

Select this component when a high-current 5 A rating is required within a wide 45 V input window. The QFN package offers a smaller footprint compared to SOIC alternatives like the MP6613GF-Z. Consider the thermal performance characteristics of the QFN package relative to the expected duty cycle and ambient operating environment.

Part Context

This part belongs to the MP6613 series of simple H-bridge drivers from Monolithic Power Systems. It provides a cost-effective alternative to discrete MOSFET solutions while maintaining robust performance. The series is designed for applications requiring reliable motor control without complex external circuitry.

Replacement Considerations

MP6613GV-P is listed as a parameter-equivalent substitute.
