ANALOG DEVICES ADE7761B handbook
The ADE7761B is an energy measurement IC with on-chip fault and missing neutral detection. It supports the IEC 62053-21 standard and offers high accuracy and a large dynamic range. The IC provides active power on the frequency outputs for calibration. It continuously monitors phase and neutral current for fault detection in 2-wire distribution systems. It also continuously monitors voltage and current inputs for missing neutral detection. The IC is designed for current channel input using shunt or current transformer sensors, and uses the larger of the two currents (phase or neutral) for billing, even during a fault condition.

Questions answered in these manuals
How does the ADE7761B indicate a missing neutral condition?
When no input voltage is present, the FAULT pin goes high to signal a missing neutral condition, and the device continues billing based on the active current signal.
What supply voltage does the ADE7761B require?
The device operates from a single 5 V supply with a tolerance of ±5 %.
