The Teridian™ 78M6631-IM/F from Analog Devices / Maxim Integrated is a sophisticated 3-phase power measurement and monitoring system-on-chip (SoC). It features a 10 MHz 8051-compatible MPU core and a 22-bit delta-sigma converter with a 32-bit compute engine.
Designed for accuracy, this IC provides better than 0.5% watt accuracy over a wide 2000:1 dynamic range and across temperature variations. It supports both Delta and Wye configurations and includes six analog inputs for voltage and current sensing. The integrated MPU core and 128 KB of flash memory allow for flexible configuration, post-processing, and host communication via UART or SPI interfaces.
This device exceeds IEC 62053/ANSI C12.20 standards and features a voltage reference with less than 40 ppm/°C stability. It operates at a 2V supply and consumes 9.1mA. The 78M6631-IM/F is packaged in a 56-TQFN (7x7) surface-mount package, making it suitable for various power monitoring systems.
Key features include True RMS calculations, active, reactive, apparent, and harmonic power calculations, line frequency, and power factor calculations. It also includes built-in calibration routines and programmable alarm thresholds.
