Polyphase Energy Metering IC with Pulsed

Output

Preliminary Technical Data

ADE7752B

FEATURES

High accuracy supports 50 Hz/60 Hz IEC62053-21

The no-load threshold and reverse polarity indication are based

on the sum of the three phase energies in the ADE7752B. The

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

Direct drive for electromechanical counters and 2-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

ADE7752B specifications surpass the accuracy requirements as

quoted in the IEC62053-21 standard.

The only analog circuitry used in the ADE7752B is in the

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

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 ADE7752B 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

interface with an MCU. The CF logic output gives

On-chip creep protection (no load threshold) based on the sum

of the three phases

instantaneous active power information. This output is

intended to be used for calibration purposes.

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

The ADE7752B includes a power supply monitoring circuit on

the V_DDpin. The ADE7752B remains inactive until the supply

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

ADE7752B also resets and no pulses are issued on F1, F2, and CF.

GENERAL DESCRIPTION

The ADE7752B¹is an accurate active energy measurement IC

intended for use in any 3-phase distribution system and has

enhanced features that make it better suited for 3-phase 3-wire

applications compared to the ADE7752/52A.

Internal phase matching circuitry ensures that the voltage and

current channels are phase matched. An internal no load

threshold ensures the ADE7752B does not exhibit any creep

when there is no load.

The ADE7752B is available in a 24-lead SOIC package.

¹Patent pending.
