ADE7761
GENERAL DESCRIPTION
(continued from Page 1)
The ADE7761 incorporates a missing neutral detection scheme
by continuously monitoring the input voltage. When a missing
neutral condition is detected—no voltage input—the ADE7761
continues billing based on the active current signal (see the
Missing Neutral Mode section). The missing neutral condition
is indicated when the FAULT pin goes high.
The ADE7761 includes a power supply monitoring circuit on
the VDD supply pin. Internal phase matching circuitry ensures
that the voltage and current channels are matched. An internal
no-load threshold ensures that the ADE7761 does not exhibit
any creep when there is no load.
The ADE7761 supplies average active power information on the
low frequency outputs F1 and F2. The CF logic output gives
instantaneous active power information.
