MPQ5029GD-AEC1-P

Overview

The MPQ5029GD-AEC1-P is an automotive-grade USB charging port controller and switch IC designed for vehicle infotainment systems. It integrates Class Load Switch (CLS) functionality and short-to-battery protection to manage multiple USB ports safely. The device operates within a supply voltage range of 3.6 V to 12 V, with a maximum operating voltage of 24 V. Key electrical parameters include a maximum on-resistance of 45 mOhms, a quiescent current of 220 uA, and power dissipation capability of 3.29 W. It supports temperatures from -40°C to +125°C and is housed in a QFN-14 package.

Procurement Notes

Verify the complete part number including suffixes such as GD and AEC1-P to ensure correct packaging, temperature grade, and automotive qualification status. Confirm that the specific revision matches the design requirements for load switch thresholds and protection timing. Cross-reference with official Monolithic Power Systems documentation to validate pinout compatibility and thermal performance specifications before finalizing procurement orders.

Selection Notes

Select this component when designing automotive USB interfaces requiring integrated load switching and fault protection in a compact form factor. The QFN-14 package offers a balance between thermal performance and board space efficiency. Ensure the input voltage range aligns with the vehicle's 12V or 24V nominal architecture. Consider the 45 mOhm on-resistance for power loss calculations in high-current charging scenarios.

Part Context

This device belongs to the MPQ5029 series of USB switch controllers manufactured by Monolithic Power Systems. It is specifically engineered for the automotive sector, distinguishing itself through AEC-Q100 certification. The series focuses on simplifying USB port management by combining switching, classification, and protection functions into a single monolithic solution, reducing bill-of-materials complexity for OEMs.

Replacement Considerations

Check for other variants within the MPQ5029 family, such as MPQ5029GD-C-AEC1-P, which may share similar functional characteristics but differ in packaging or specific electrical tolerances. Verify pin-to-pin compatibility and parameter equivalence before substituting any alternative part numbers.
