ADE7868 Poly Phase Multifunction Energy Metering IC with Tamper Detection and Low Power Mode
The ADE7868 is a high accuracy, 3-phase electrical energy
measurement IC with serial interfaces and three flexible pulse
outputs. The ADE7868 incorporates second-order Σ-Δ ADCs, a
digital integrator, reference circuitry, and all the signal
processing required to perform total (fundamental and
harmonic) active, reactive and apparent energy measurement,
and rms calculations. A fixed function digital signal processor
(DSP) executes this signal processing.
The ADE7868 is suitable to measure active, reactive, and
apparent energy in various 3-phase configurations, such as
WYE or DELTA services, with both three and four wires. The
ADE7868 provides system calibration features for each phase,
that is, rms offset correction, phase calibration, and gain
calibration. The CF1, CF2 and CF3 logic outputs provide a wide
choice of power information: total active/reactive/apparent
power or sum of current rms values.
The ADE7868 has waveform sample registers that allow access
to all ADC outputs. The device also incorporates power quality
measurements such as short duration low or high voltage
detections, short duration high current variations, line voltage
period measurement and angles between phase voltages and
currents. Two serial interfaces can be used to communicate with
the ADE7868: SPI or I2C while a dedicated high speed interface,
HSDC (High Speed Data Capture) port, can be used in
conjunction with I2C to provide access to the ADC outputs and
real time power information. The ADE7868 has also two
interrupt request pins, IRQ0 and IRQ1, to indicate that an
enabled interrupt event has occurred.
Three specially designed low power modes ensure the
continuity of the energy accumulation when the ADE7868 is in
tampering situation.
The ADE7868 is available in 40-lead LFCSP lead free package.
