MP6605DGR-Z

Overview

The MP6605DGR-Z is a low-side motor driver from Monolithic Power Systems, designed for automotive and industrial applications. It features four independent channels capable of sourcing up to 1.5 A per output. The device operates within a supply voltage range of 4.5 V to 60 V and supports PWM control signals. It is housed in a QFN-24 surface-mount package with a maximum power dissipation of 2.9 W. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Four-channel low-side driver architecture for independent load control
• Supports pulse-width modulation (PWM) input signals for precise regulation
• Integrated thermal protection mechanisms for operational safety

Applications

• Automotive lighting systems including headlights and interior illumination
• Industrial motor control circuits requiring low-side switching
• Solenoid and valve actuation in motion control applications

Procurement Notes

Verify the specific suffix Z indicates lead-free compliance against the manufacturer datasheet. Confirm the QFN-24 package dimensions match your PCB footprint requirements. Ensure the 60V rating aligns with your system's peak voltage transients. Check for RoHS certification status if required by your manufacturing standards.

Selection Notes

Select this component when driving multiple low-side loads such as lamps or small motors from a single controller. The 1.5A per channel capacity suits moderate current applications without external heat sinking in most scenarios. Consider the QFN-24 package for space-constrained designs requiring efficient thermal management through the exposed pad.

Part Context

This part belongs to the MP6605 series of power management ICs focused on motor and ignition drivers. It complements other MPS solutions like the MP6515 for different bridge configurations. The series targets robust performance in noisy electrical environments typical of automotive and industrial sectors.

Replacement Considerations

Direct substitutes include the MP6605DGR-P variant which shares identical electrical specifications but differs in packaging quantity. Verify pin compatibility before swapping between reel and cut-tape versions.
