Polyphase Energy Metering IC with Phase

Drop Indication

Preliminary Technical Data

ADE7762

FEATURES

The only analog circuitry used in the ADE7762 is in the

analog-to-digital converters (ADCs) and reference circuit. All

High accuracy supports 50 Hz/60 Hz IEC62053-21

Less than 0.1% error over a dynamic range of 500 to 1

Compatible with 3-phase 3-wire delta and 3-phase 4-wire Wye

configurations

Supplies average active power on the frequency outputs F1 and F2

High frequency output (CF) is intended for calibration and

supplies instantaneous active power

Logic output REVP indicates a potential miswiring or negative

power on the sum of all phases

Dropout indication for each phase on LED driver pins

Phase sequence error detection

Direct drive for electromechanical counters and 2-phase stepper

motors (F1 and F2)

other signal processing (for example, 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 ADE7762 supplies average active power information on the

low frequency outputs, F1 and F2. These logic outputs can be

used to directly drive an electromechanical counter or to inter-

face with an MCU. The CF logic output gives instantaneous

active power information. This output is intended to be used for

calibration purposes.

The ADE7762 includes a power supply monitoring circuit on the

V_DDpin. The ADE7762 remains inactive until the supply voltage

on V_DDreaches 4 V. If the supply falls below 4 V, the ADE7762

also resets and no pulses are issued on F1, F2, and CF.

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% (25 ppm/°C typical) with external

overdrive capability

Single 5 V supply, low power (TBD mW typical)

Low cost CMOS process

A multiple multiplexed logic output provides phase dropout per

phase, reverse polarity per phase, and a phase sequence error.

Internal phase matching circuitry ensures that the voltage and

current channels are phase matched. An internal no load

threshold ensures the ADE7762 does not exhibit any creep

when there is no load.

GENERAL DESCRIPTION

The ADE7762¹is a high accuracy polyphase electrical energy

measurement IC. The ADE7762 specifications surpass the

accuracy requirements as quoted in the IEC62053-21 standard.

The ADE7762 is available in a 28-lead SOIC package.

¹Patent pending.
