ADE7752B
Preliminary Technical Data
POWER SUPPLY MONITOR
The ADE7752B contains an on-chip power supply monitor. The
power supply (V
DD
) is monitored continuously by the ADE7752B.
At power up, when the supply is less than 4V ±2% and V
REF
is less
than 1.9 V (typ), the outputs of the ADE7752B are inactive and
the data path is held in reset. Once V
DD
is greater than 4V ±2%
and V
REF
is greater than 1.9 V (typ), the chip is active and energy
accumulation begins. At power-down, when V
DD
falls below 4 V
or V
REF
falls below 1.9 V (typ), 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.
