Power monitoring IC with high-accuracy signal acquisition, power calculations

MICROCHIP TECHNOLOGY MCP39F501 power monitoring IC is a highly integrated, single-phase device designed for real-time measurement of AC power and includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. Devcie allows designers to add power monitoring to their applications with minimal firmware development. Product’s performance enables designs capable of 0.1% error over a wider dynamic range and superior light load measurement versus current competing solutions.
