ADE7752

Preliminary Technical Data

FEATURES

GENERALDESCRIPTION

High Accuracy, Supports 50 Hz/60 Hz IEC 687/1036

Less than 0.1% Error Over a Dynamic Range of

500 to 1

Compatible with 3-phase/3-wire and 3-phase/4-wire

configurations

The ADE7752 is a high accuracy three phase electrical

energy measurement IC. The part specifications surpass the

accuracy requirements as quoted in the IEC1036 standard.

The only analog circuitry used in the ADE7752 is in the

ADCs and reference circuit. All other signal processing (e.g.,

multiplication, 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

interface with an MCU. The CF logic output gives instan-

taneous real power information. This output is intended to be

used for calibration purposes, or as interface with an MCU.

The ADE7752 includes a power supply monitoring circuit

on the AV_DDsupply pin. The ADE7752 will remain inactive

until the supply voltage on V_DDreaches 4 V. If the supply falls

below 4 V, the ADE7752 will also be reset and no pulses will

be issued on F1, F2 and CF.

The ADE7752 Supplies Average Real Power on the

Frequency Outputs F1 and F2

The High Frequency Output CF Is Intended for

Calibration and Supplies Instantaneous Real Power

The Logic Output REVP indicates a Potential Miswiring or

Negative Power for each phase

Direct Drive for Electromechanical Counters and

Two Phase 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 2.5 V 8% (30 ppm/8C Typical)

with External Overdrive Capability

Single 5 V Supply, Low Power (15 mW Typical)

Low Cost CMOS Process

Internal phase matching circuitry ensures that the voltage and

current channels are phase matched. An internal no-load

threshold ensures that the ADE7752 does not exhibit any

creep when there is no load.

The ADE7752 is available in 24-lead SOIC packages.
