MPQ7731DF-AEC1-LF-Z

Overview

The MPQ7731DF-AEC1-LF-Z is a mono, 5W to 30W Class D audio amplifier manufactured by Monolithic Power Systems. It integrates full-bridge MOSFETs with an on-resistance of 180mΩ and operates within a supply voltage range of 9.5V to 18V. The device delivers up to 5A output current into a 4Ω load and functions in the -40°C to +125°C temperature range. Packaged in a 20-TSSOP with an exposed pad, it supports AEC-Q100 automotive qualification standards.

Feature Summary

Integrates high-efficiency full-bridge power MOSFETs for compact design
Includes comprehensive protection mechanisms such as thermal shutdown and short-circuit protection
Features integrated pop-suppression and mute control capabilities

Applications

Automotive infotainment systems
Embedded electronics requiring high-fidelity audio
Industrial equipment with audio output requirements

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific suffix indicates AEC-Q100 automotive qualification status. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Validate package integrity against the specified 20-TSSOP dimensions.

Selection Notes

Select this component for applications demanding high efficiency and minimal external passive components. The integrated MOSFETs reduce board space compared to discrete solutions. Verify that the input voltage range aligns with the system power supply. Consider the thermal performance of the exposed pad for heat dissipation in enclosed environments.

Part Context

This part belongs to the MPQ7731 series of second-generation fully integrated Class D audio amplifiers from Monolithic Power Systems. The series focuses on providing high power density and reliability for demanding audio applications. The AEC1 suffix denotes compliance with automotive electronic council quality standards.

Replacement Considerations

MPQ7731DF-LF-Z is a non-automotive qualified variant of the same functional device. Verify if automotive certification is strictly required before substituting.
