Microchip has introduced two fully functional, standalone energy-measurement ICs that output average and instantaneous real power.
These analog front ends, the MCP3905 and MCP3906, can be paired with a PIC microcontroller to provide a complete, highly accurate solution for single-phase electronic energy measurement in residential power meters and industrial applications.
The devices each integrate two 16-bit delta-sigma analog-to-digital converters, an internal voltage reference, and all the digital circuitry needed to calculate average and instantaneous real power. The MCP3905 features a programmable gain amplifier (PGA) with a maximum gain of 16, while for higher accuracy applications, the MCP3906 has a maximum gain of 32. Both devices can meet or exceed the requirements of IEC62053 energy-metering specifications.
The new ICs provide high accuracy, with a 0,1% typical measurement error over a 500:1 dynamic range for the MCP3905 or a 1000:1 dynamic range for the MCP3906. A low-drift, on-chip voltage reference ensures that measurements do not change during the life of the meter. The devices have a low current consumption of 4 mA, support direct drive for both mechanical counters and two-phase stepper motors, include a tamper output pin for negative power indication, and operate over a temperature range of -40 to +85°C.
To support energy-meter application development, Microchip also offers the MCP3905 Energy Meter Reference Design Board and the MCP3905 Energy Meter Evaluation Board. Microchip has also launched a new online Utility Meter Design Centre (www.microchip.com/meter), which provides engineers with technical tools and resources.
