AI-Accelerated DC Arc Fault Circuit Interrupter Reference Design

The DC-AFCI-MCXN547 reference design helps engineers develop AI-accelerated DC arc fault circuit interrupter solutions for solar PV inverters and DC energy systems. Built around the MCXN547 MCU, it combines multi-channel sensing, PowerQuad FFT acceleration, on-chip NPU inference and eIQ Time Series Studio workflow to speed data collection, model training, validation and deployment.
