CHANDLER, AZ -- Microchip Technology Inc. expands its power-monitoring IC portfolio with the addition of the MCP39F511N. Capable of providing popular standard power calculations and event monitoring of two electrical loads, this highly integrated and accurate device facilitates system design and reduces system cost of power-monitoring wall outlets and smart plugs, power strips, AC/DC power supplies and power distribution applications. It includes three Analog-to-Digital Converters (ADCs) for voltage and two current load measurements, 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 current measurement channel allows the MCP39F511N to monitor two current loads with just 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 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 now for $200.
Pricing & Availability
The MCP39F511N is available now for sampling and volume production in a 28-lead, 5x5 mm QFN package. It is priced at $1.82 each, in 5,000-unit quantities.
