MPQ5029GD-AEC1-Z

Overview

The MPQ5029GD-AEC1-Z is an AEC-Q100 qualified USB charging port controller with an integrated current limit switch and short-to-battery protection, designed for automotive applications. It supports a maximum operating supply voltage of 24 V and features a maximum on-resistance of 45 mOhms. The device operates within a temperature range of -40°C to +125°C and consumes 220 uA of operating supply current. Packaged in a QFN-14 surface-mount format, it dissipates up to 3.29 W of power.

Feature Summary

• Integrated current limit switch with short-to-battery protection
• Supports USB charging protocols including CDP, DCP, and QC3.0
• Automotive-grade qualification compliant with AEC-Q100 standards

Applications

• Automotive infotainment systems
• Vehicle docking stations
• Car charger hubs

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and lead-free status as per Monolithic Power Systems documentation. Confirm the package type matches the QFN-14 specification required for your PCB layout. Ensure the component meets the AEC-Q100 grade requirements for your automotive design validation process before finalizing procurement.

Selection Notes

Select this component when designing automotive USB interfaces requiring integrated protection against short circuits to the battery rail. It is suitable for applications needing support for fast charging standards like Quick Charge 3.0 alongside standard USB charging detection. Consider its 45 mOhm on-resistance for thermal management in high-current scenarios.

Part Context

This part belongs to the MPQ5029 series from Monolithic Power Systems, specifically tailored for automotive environments. It combines port control logic with power switching capabilities, eliminating the need for external protection components. The AEC1 suffix denotes its qualification for automotive reliability standards.

Replacement Considerations

Check for MPQ5029GD-C-AEC1-Z if specific protocol compatibility adjustments are needed. Verify pinout and thermal characteristics against alternative USB controllers from other manufacturers to ensure mechanical and electrical interchangeability without redesigning the host circuitry.
