MA5302MSXUMA1

Audio Amplifiers Overview

The MA5302MS is a MERUS™ 2x200W Class-D audio amplifier with analog input and an integrated 16mΩ RDS(ON) output stage. It delivers 2 x 200W in stereo mode (2Ω, THD=10%) or 1 x 400W in mono mode (4Ω, THD=10%). The device supports split supplies from ±17V to ±32V and single supplies from +32V to +64V. It achieves 95% full-load efficiency into 2Ω and features open-drain flag indicators for clipping and fault conditions. Available in a QFN 7mm x 7mm – 42 pin package.

Audio Amplifiers Feature Summary

• Integrates a 2-channel PWM controller, high voltage gate driver, and four low RDS(ON) MOSFETs within a multi-chip module solution.
• Supports multiple configuration modes including single-ended, bridge-tied load (BTL), and parallel single-ended (PSE).
• Includes programmable power-up delay timer for click-and-pop-free startup and shutdown sequences.
• Provides integrated protection mechanisms such as over-current protection (OCP), over-temperature protection (OTP), and under-voltage lockout (UVLO).

Audio Amplifiers Applications

• Multi-channel home theatre systems
• Studio monitors
• Active speakers
• Subwoofers
• Marine amplifiers

Audio Amplifiers Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm packaging type and reel specifications. Ensure compatibility with J-STD-020 moisture sensitivity level requirements during storage and handling. Confirm that the application design adheres to the recommended operating conditions for supply voltages and thermal management to maintain device reliability.

Audio Amplifiers Selection Notes

Select this component for designs requiring high power density and heatsink-less operation in compact form factors. Consider its pin-to-pin compatibility with the MA53x2 family if upgrading existing architectures. Evaluate the need for BTL or PSE configurations based on target speaker impedance and desired output power levels.

Audio Amplifiers Part Context

The MA5302MS belongs to the MERUS™ integrated Class-D amplifier family, representing a significant upgrade over previous monolithic alternatives like the IR43x2M. It utilizes advanced co-packaging techniques to reduce space by 50% while maintaining high performance. This series targets applications demanding superior audio quality and energy efficiency in small footprints.

Audio Amplifiers Replacement Considerations

Pin-to-pin compatible with other members of the MA53x2 family. Verify specific power ratings and impedance matching when substituting with variants like MA5332MS or MA5342MS.
