MCP39F511 Energy Measurement ICs

The MCP39F511 from Microchip is an integrated, single-phase power monitoring device that provides real-time measurement of input power and energy values for AC/DC power supplies. On-board are two Delta-Sigma Analogue-to-Digital Converters (ADCs), a 16-bit Calculation Engine, EEPROM and a flexible 2-Wire Interface. An integrated low-drift voltage reference, combined with the 94.5 dB of SINAD performance on each measurement channel, allows for better than 0.1% accurate designs across a 4000:1 dynamic range.


Power monitoring accuracy capable of 0.1% error across 4000:1 dynamic range
Built-in calculations using a 16-Bit processing core measuring:
- Active, reactive and apparent Power
- Active and reactive energy accumulation
- True RMS current, RMS voltage
- Line frequency, power factor
Dedicated Zero Crossing Detection (ZCD) pin
Dedicated PWM output pin
Automatic event pin control through fast voltage surge detection
Fast calibration routines
2-wire UART with 115.2k baud rate
