MA5332MS

Overview

MERUS™ 2-channel analog input class D audio amplifier multichip module

The MERUS™ MA5332MS multichip module offers the same or even higher output power as monolithic alternatives without a heatsink and 50 percent less footprint. This MCM (multi-chip module) solution integrates a dual-channel PWM controller, high-voltage gate driver, and 4 low RDS(ON) MOSFETs. Like its predecessor, IR43x2M, it includes standard class D protection features for reliable operation over various environmental conditions. As a powerful upgrade to IR43x2M and other monolithic solutions, the MA5332MS’ 7x7 mm PG- IQFN-42 package showcases the benefit of a small footprint, high power density, and operation without a heatsink.

Summary of Features

  • 2-channel analog input class D audio amplifier in a small 7x7mm package
  • Very low RDS(ON) @ 24.4 mΩ typical, enabling operation without a heatsink at 2x100W at 4Ω
  • 95% efficiency class D at 2x200W at 4Ω
  • Split or single power supply capable
  • Differential or single-ended input
  • Multiple configuration options: 2xSE, BTL, PSE (parallel single-ended)
  • Over-current, over-temperature and under-voltage protections with self-reset feature
  • Start/stop click noise reduction
  • Clip and fault reporting outputs

Benefits

  • Enables heatsink-less solution comparing to same power level monolithic approach
  • Enables high power SE (single-ended)
  • Designs with reduced bus capacitors and output filters based on a low voltage BTL approach
  • Simplifies class D design and eliminates the needs for external protection circuitry

Potential Applications

  • Multi-channel home theatre system
  • Studio monitor
  • Active speaker
  • Soundbar subwoofer
  • Marine amplifier
  • Aftermarket car audio system
  • General-purpose audio power amplifier
