Monitor IC measures AC power in real-time
The single-phase power-monitoring IC includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with just 0.1 % error across a 4000:1 dynamic range. The IC allows designers to add power monitoring to an applications with minimal firmware development. To improve power-management schemes in power-hungry applications, such as data centres, lighting and heating systems, industrial equipment and consumer appliances, enhanced power monitoring includes requirements for better accuracy across current loads, additional power calculations and event monitoring of various power conditions. The IC's built-in calculations include active, reactive and apparent power, RMS current and RMS voltage, line frequency, power factor as well as programmable event notifications.
