The MA5342MS is optimized for 4-16 Ω speaker impedances. It offers the same or higher output power than monolithic alternatives without heatsink and 50% less footprint. This MCM solution integrates 2 channel PWM controller, high voltage gate driver, and 4 low RDS(ON) MOSFETs. It includes standard class D protection features for reliable operation over various environmental conditions. MA5342MS has the same 7x7 mm PG- IQFN-42 package as MA5332MS.
Summary of Features
Small 7x7 mm package
Heatsink-less operation at 2x144 W at 8 Ω
150 V rating of the integrated MOSFETs
95% efficiency Class D at 2x210 W at 8 Ω
Split or single power supply capable
Differential or single-ended input
2xSE, BTL, PSE (Parallel Single-Ended)
OCP, OTP, and UVP with self-reset
Start/stop click noise reduction
Clip and Fault reporting outputs
Benefits
Enables heatsink-less solution
Reduced bus caps and output filters
No needs for external protections
Potential Applications
AV receiver
Home theater
Multi-room amplifier
Marine amplifier
Active speaker
Studio monitor
General-purpose audio power amplifier
