stepper motors (F1 and F2)
Proprietary ADCs and DSP provide high accuracy over large
variations in environmental conditions and time
On-chip power supply monitoring
On-chip creep protection (no load threshold)
On-chip reference 2.4 V ±8% (20 ppm/°C typical) with
external overdrive capability
Single 5 V supply, low power
60 mW typical: ADE7752
30 mW typical: ADE7752A
Low cost CMOS process
GENERAL DESCRIPTION
The ADE7752 is a high accuracy polyphase electrical energy
measurement IC. The ADE7752A is a pin-to-pin compatible
low power version of ADE7752. The functions of ADE7752 and
ADE7752A are the same. Both products are referred to in the
text of this data sheet as ADE7752.
The part specifications surpass the accuracy requirements as
quoted in the IEC62053-2x standard. The only analog circuitry
used in the ADE7752 is in the analog-to-digital converters (ADCs)
and reference circuit. All other signal processing (such as multi-
plication, filtering, and summation) is carried out in the digital
domain. This approach provides superior stability and accuracy
over extremes in environmental conditions and over time.
The ADE7752 supplies average real power information on the
low frequency outputs, F1 and F2. These logic outputs may be
used to directly drive an electromechanical counter or to
interface with an MCU. The CF logic output gives instanta-
neous real power information. This output is intended to be
used for calibration purposes.
The ADE7752 includes a power supply monitoring circuit on
the VDD pin. The ADE7752 remains inactive until the supply
voltage on VDD reaches 4 V. If the supply falls below 4 V, no
pulses are issued on F1, F2, and CF. Internal phase matching
circuitry ensures that the voltage and current channels are
phase matched. An internal no load threshold ensures the part
does not exhibit any creep when there is no load. The ADE7752
is available in a 24-lead SOIC package.
