MPQ5029GD-C-AEC1-P

Overview

The MPQ5029GD-C-AEC1-P is an automotive-grade USB charging port controller and switch IC from Monolithic Power Systems. It supports CDP, DCP, and QC3.0 charging modes with integrated current limit sensing (CLS) and short-to-battery protection. The device operates on a supply voltage of 3V to 24V, with a maximum on-resistance of 45 mOhms and a quiescent current of 220 uA. It features a QFN-14 package, handles up to 3.29 W power dissipation, and functions within a temperature range of -40°C to +125°C. AEC-Q100 qualified for automotive applications.

Feature Summary

• Supports multiple fast-charging protocols including Qualcomm Quick Charge 3.0, Dedicated Charging Port (DCP), and Combined Device/Charger Port (CDP) modes.
• Integrates current limit sensing (CLS) and short-to-battery protection for enhanced system safety and reliability.
• Designed specifically for automotive environments with AEC-Q100 qualification and extended temperature operation.

Applications

• Automotive infotainment systems requiring USB charging ports
• Vehicle dock stations and connectivity hubs
• Aftermarket automotive electronics with USB interfaces

Procurement Notes

Verify the specific suffix 'C' against official MPS documentation to confirm protocol support differences compared to other variants. Ensure the AEC-Q100 qualification status matches your project's automotive grade requirements. Confirm the QFN-14 package dimensions and thermal characteristics align with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when automotive-grade USB charging control is required with support for Quick Charge 3.0 and standard charging profiles. Consider the low quiescent current for battery-sensitive applications. Evaluate the 45 mOhm on-resistance for efficiency needs in high-current charging scenarios. Ensure compatibility with the host system's logic levels and communication interfaces.

Part Context

This part belongs to the MPQ5029 series of USB switch controllers by Monolithic Power Systems. It is designed to replace discrete solutions for USB port management in vehicles. The series offers integrated protection and charging negotiation capabilities, simplifying design complexity for automotive OEMs and Tier 1 suppliers developing connected car solutions.

Replacement Considerations

Check MPS datasheets for direct pin-compatible alternatives within the MPQ5029 family. Verify if the 'Z' or 'P' suffix variants offer identical electrical characteristics. Cross-reference with other automotive USB controllers if protocol support differs significantly.
