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. The zero-crossing detection
is used inside the chip for the line cycle energy accumulation
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.
