Single-Phase Multifunction Metering IC

with di/dt Sensor Interface

ADE7753

line-voltage period measurement, and rms calculation on the

voltage and current. The selectable on-chip digital integrator

provides direct interface to di/dt current sensors such as

FEATURES

High accuracy; supports IEC 60687/61036/61268 and

IEC 62053-21/62053-22/62053-23

Rogowski coils, eliminating the need for an external analog

integrator and resulting in excellent long-term stability and pre-

cise phase matching between the current and voltage channels.

On-chip digital integrator enables direct interface to current

sensors with di/dt output

A PGA in the current channel allows direct interface to

shunts and current transformers

The ADE7753 provides a serial interface to read data, and a

pulse output frequency (CF), which is proportional to the active

power. Various system calibration features, i.e., channel offset

correction, phase calibration, and power calibration, ensure

high accuracy. The part also detects short duration low or high

voltage variations.

Active, reactive, and apparent energy; sampled waveform;

current and voltage rms

Less than 0.1% error in active energy measurement over a

dynamic range of 1000 to 1 at 25°C

Positive-only energy accumulation mode available

On-chip user programmable threshold for line voltage surge

and SAG and PSU supervisory

The positive-only accumulation mode gives the option to

accumulate energy only when positive power is detected. An

internal no-load threshold ensures that the part does not exhibit

any creep when there is no load. The zero-crossing output (ZX)

produces a pulse that is synchronized to the zero-crossing point

of the line voltage. This signal is used internally in the line cycle

active and apparent energy accumulation modes, which enables

faster calibration.

Digital calibration for power, phase, and input offset

On-chip temperature sensor ( 3°C typical)

SPI® compatible serial interface

Pulse output with programmable frequency

IRQ

Interrupt request pin (

) and status register

Reference 2.4 V with external overdrive capability

Single 5 V supply, low power (25 mW typical)

GENERAL DESCRIPTION

The ADE7753¹features proprietary ADCs and DSP for high

accuracy over large variations in environmental conditions and

time. The ADE7753 incorporates two second-order 16-bit -Δ

ADCs, a digital integrator (on CH1), reference circuitry,

temperature sensor, and all the signal processing required to

perform active, reactive, and apparent energy measurements,

The interrupt status register indicates the nature of the interrupt,

and the interrupt enable register controls which event produces

IRQ

an output on the

pin, an open-drain, active low logic output.

The ADE7753 is available in a 20-lead SSOP package.
