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 supplies average active power information on the

low frequency outputs F1 and F2. The CF logic output gives

instantaneous active power information.

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.
