Microchip Technology Inc. has introduced the MCP39F511N as the latest addition to its power monitoring IC portfolio. According to the company, the highly integrated and accurate device is capable of providing popular standard power calculations and event monitoring of two electrical loads, and can ease system design and slash system cost of power-monitoring wall outlets and smart plugs, power strips, AC/DC power supplies and power distribution applications.

The MCP39F511N includes three analogue to digital convertors (ADCs) for voltage and two current load measurements, a 16bit calculation engine, EEPROM and a flexible 2-wire interface.


An integrated low-drift voltage reference in addition to the 94.5dB of SINAD performance on each current measurement channel allows the MCP39F511N to monitor two current loads with just 0.5 per cent 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 allows system designers of high-performance devices to reduce bill of materials and reduce time-to-market.

The MCP39F511N is supported by Microchip's MCP39F511N Power Monitor Demonstration Board (part ADM00706), which is available for ₹13,422.82 ($200) via any Microchip sales representative or authorised worldwide distributor, or from microchipDIRECT.
