ADE7953
ADE7953 POWER-UP PROCEDURE
The ADE7953 contains an on-chip power supply monitor that
supervises the power supply (VDD). While the voltage applied
to the VDD pin is below 2 V ± 10%, the chip is in an inactive
state. Once VDD crosses the 2 V ± 10% threshold, the power
supply monitor keeps the ADE7953 in an inactive state for an
additional 26 ms. This time delay allows VDD to reach the
minimum specified operating voltage of 3.3 V – 10%. Once
the minimum specified operating voltage is met, the internal
circuitry is enabled; this is accomplished in approximately
40 ms.
Once the start-up sequence is complete and the ADE7953 is
ready to receive communication from a microcontroller, the
reset flag is set in the IRQSTATA register (Address 0x22D and
Address 0x32D). An external interrupt is triggered on the IRQ
pin. The reset interrupt is enabled by default and cannot be
Data Sheet
Once the start-up sequence is complete, communication with
the ADE7953 can begin. See the Communicating with the
ADE7953 section for further details.
REQUIRED REGISTER SETTING
For optimum performance, Register Address 0x120 must be
configured by the user after powering up the ADE7953 . This
register ensures that the optimum timing configuration is
selected to maximize the accuracy and dynamic range. This
register is not set by default and thus must be written by the
user each time the ADE7953 is powered up. Register 0x120 is
a protected register and thus a key must be written to allow the
register to be modified. The following sequence should be
followed:
? Write 0xAD to Register Address 0xFE:This unlocks
disabled, hence an external interrupt always occurs at the end
of a power-up procedure, hardware or software reset.

It is highly recommended that the reset interrupt is used by
the microcontroller to gate the first communication with the
ADE7953 . If the interrupt is not used, a timeout can be

implemented; however, as the start-up sequence can vary part-
to-part and over temperature, a timeout of a least 100 ms is
recommended. The reset interrupt provides the most efficient
way of monitoring the completion of the ADE7953 start-up
sequence.
