Microchip Technology recently expanded its power-monitoring IC portfolio with the addition of the MCP39F511N, which provides standard power calculations and event monitoring of two electrical loads. It includes three ADCs for voltage and two current load measurements, a 16-bit calculation engine, EEPROM, and a flexible two-wire interface.
An integrated low-drift voltage reference in addition to the 94.5 dB of SINAD performance on each current measurement channel enables the MCP39F511N to monitor two current loads with only 0.5% error across a wide 4000:1 dynamic range. The ability to measure active, reactive and apparent power, active and reactive energy accumulation, RMS current and RMS voltage, line frequency, and power factor combined with advanced, integrated features enables you to reduce bill of materials and time to market.
The MCP39F511N is supported by Microchip Technology’s $200 MCP39F511N Power Monitor Demonstration Board (ADM00706). The MCP39F511N is available for sampling and volume production in a 28-lead, 5 × 5 mm QFN package. It costs $1.82 in 5,000-unit quantities.
