ADE7762
POWER SUPPLY MONITOR
The ADE7762 contains an on-chip power supply monitor. The
power supply (V DD ) is monitored continuously. At power-up,
when the supply is less than 4 V ± 2% and V REF is less than 1.9 V
(typical), the outputs of the ADE7762 are inactive and the data
path is held in reset. Once VDD is greater than 4 V ±2% and
VREF is greater than 1.9 V (typical), the chip is active and energy
accumulation begins. At power-down, when VDD falls below
4 V or V REF falls below 1.9 V (typical), the data path is again held
in reset. This implementation ensures correct device operation
at power-up and at power-down. The power supply monitor

has built-in hysteresis and filtering. This gives a high degree of
immunity to false triggering due to noisy supplies.

The power supply and decoupling for the part should be such
that the ripple at V DD does not exceed ±5% as specified for
normal operation.
