GENERAL DESCRIPTION
The ADE7754 is a high accuracy polyphase electrical energy
measurement IC with a serial interface and a pulse output. The
ADE7754 incorporates second order Σ - ? ADCs, reference
circuitry, temperature sensor, and all the signal processing
required to perform active, apparent energy measurements, and
rms calculation.
The ADE7754 provides different solutions for measuring active
the use of the ADE7754 in various power meter services such as
3-phase/4-wire, 3-phase/3-wire, and 4-wire delta.
In addition to rms calculation, active and apparent power infor-
mation, the ADE7754 provides system calibration features for
each phase (i.e., channel offset correction, phase calibration,
and gain calibration). The CF logic output provides instanta-
neous active power information.
The ADE7754 has a waveform sample register that enables
access to ADC outputs. The part also incorporates a detection
circuit for short duration low or high voltage variations. The
voltage threshold levels and the duration (number of half line
cycles) of the variation are user programmable.
A zero-crossing detection is synchronized with the zero-crossing
point of the line voltage of each of the three phases. The infor-
mation collected is used to measure each line’s period. It is also
used internally to the chip in the line active energy and line
apparent energy accumulation modes. This permits faster and
more accurate calibration of the power calculations. This signal
is also useful for synchronization of relay switching.
Data is read from the ADE7754 via the SPI serial interface. The
interrupt request output ( IRQ ) is an open-drain, active low
logic output. The IRQ output goes active low when one or more
interrupt events have occurred in the ADE7754. A status regis-
ter indicates the nature of the interrupt.
The ADE7754 is available in a 24-lead SOIC package.
