ADE7758
GENERAL DESCRIPTION
(Continued from Page 1)
The ADE7758 has a waveform sample register that allows access
to the 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 any of the three phases. This information can be used to
measure the period of any one of the three voltage inputs. It is
also used internally to the chip in the line cycle energy accu-
mulation mode. This mode permits faster and more accurate
calibration by synchronizing the energy accumulation with an
integer number of line cycles.
Data is read from the ADE7758 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 ADE7758. A status register
indicates the nature of the interrupt. The ADE7758 is available
in a 24-lead SOIC package.
