MPQ7795GRE-AEC1-P

Overview

The MPQ7795GRE-AEC1-P is a single-channel Class-D audio amplifier from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It delivers 24.5W of output power into a 2-ohm load using a bridge-tied load (BTL) configuration. The device operates on a single supply voltage ranging from 4.5V to 36V and supports load impedances between 2 Ohms and 16 Ohms. Key electrical specifications include a gain of 20 dB, a total harmonic distortion plus noise (THD+N) of 0.38%, and an analog input interface. It functions within a junction temperature range of -40°C to +150°C and is housed in a 24-pin QFN package.

Feature Summary

• Integrated diagnostic capabilities for system monitoring
• Low electromagnetic interference (EMI) operation at 2.2MHz switching frequency
• Automotive-grade reliability compliant with AEC-Q100 standards

Applications

• Automotive audio systems requiring high power output
• Single-channel speaker amplification in vehicles
• Applications necessitating low EMI emissions

Procurement Notes

Verify the complete part number including suffixes such as -P or -Z, as these indicate specific packaging configurations like reel or cut tape. Confirm that the AEC1 suffix aligns with required automotive qualification standards. Ensure the QFN-24 package footprint matches the design layout. Cross-reference the datasheet for thermal management requirements given the high power density and operating temperature range.

Selection Notes

Select this component when a single-channel solution is needed for automotive environments. It is suitable for driving 2-ohm loads with up to 24.5W power. Consider the 36V maximum input voltage for compatibility with vehicle power buses. The integrated diagnostics simplify fault detection. Verify that the 20dB gain and analog input interface match the source signal requirements.

Part Context

This part belongs to the MPQ7795 series of audio amplifiers by Monolithic Power Systems. The series includes variants like the MPQ7795AGRE-AEC1-Z, which shares similar core specifications but may differ in packaging or minor operational parameters. All parts in this family are targeted at automotive audio applications requiring robust performance and compliance with automotive quality standards.

Replacement Considerations

The MPQ7795AGRE-AEC1-Z is a confirmed substitute within the same product line. Both parts share identical core electrical characteristics and automotive qualifications. Differences primarily involve packaging options, with the -Z variant often associated with cut tape or Digi-Reel packaging compared to the standard reel option.
