The MA5302MS is optimized for 1-2 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. MA5302MS has the same 7x7 mm PG- IQFN-42 package as MA5332MS.
Summary of Features
Small 7x7 mm package
Heatsink-less operation at 2x102 W at 2 Ω
80 V rating of the integrated MOSFETs
94% efficiency Class D at 2x220W at 2 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 high power SE (single ended)
Reduced bus caps and output filters
No needs for external protections
Potential Applications
Soundbar subwoofer
Aftermarket car audio system
Marine amplifier
Active speaker
Studio monitor
General-purpose audio power amplifier
