Product Overview
MP8049SDU-LF-Z is an MPS configurable dual full-bridge or quad half-bridge power stage for Class-D audio and related PWM power-drive applications. The four protected half-bridges can operate as two independent full bridges or as separate half-bridge outputs.
The device integrates current limiting, undervoltage, thermal and short-circuit protection.

Power-Stage Considerations
The 5.5 A figure is a peak capability, not a continuous current guarantee. Audio load, PWM frequency, PCB copper and thermal path determine the sustainable output power.
