Status: In Production
The MCP39F521 is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies, providing power and energy values. It includes dual-channel delta sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible 2-wire interface. An integrated low-drift voltage reference in addition to the 94.5 dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
The MCP39F521 Power Monitor Demonstration Board is a fully functional I2C bus single-phase power and energy monitoring system. Up to four different devices can be placed on the same I2C bus through address select pins. The system calculates and displays active power, reactive power, RMS current, RMS voltage, active energy (both import and export), and four quadrant reactive...
