withdi/dtsensorinterface

ADE7753*

precise phase matching between the current and voltage

channels. T he integrator can be switched on and off based on

the current sensor selected.

T he AD E7753 contains an Active Energy register. It is

capable of holding more than 200 seconds of accumulated

power at full load. Data is read from the ADE7753 via the

serial interface. T he ADE7753 also provides a pulse output

(CF) with output frequency is proportional to the active

power.

In addition to rms calculation and active and apparent power

information, the AD E7753 also accumulates the signed

reactive energy. T he ADE7753 also provides various system

calibration features, i.e., channel offset correction, phase

calibration and power calibration. T he part also incorporates

a detection circuit for short duration low or high voltage

variations.

T he ADE7753 has a positive only accumulation mode which

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.

A zero crossing output (ZX) produces an output which is

synchronized to the zero crossing point of the line voltage.

T his information is used in the ADE7753 to measure the

line's period. T he signal is also used internally to the chip in

the line cycle Active and Apparent energy accumulation

mode. T his enables a faster and more precise energy accumu-

lation and is useful during calibration. T his signal is also

useful for synchronization of relay switching with a voltage

zero crossing.

GENERAL DESCRIP TION

T he AD E7753 is an accurate active and apparent energy

measurements IC with a serial interface and a pulse output.

T he ADE7753 incorporates two second order sigma delta

AD Cs, a digital integrator (on CH 1), reference circuitry,

temperature sensor, and all the signal processing required to

perform RMS calculation on the voltage and current, active,

reactive, and apparent energy measurement.

T he interrupt request output is an open drain, active low logic

output. T he Interrupt Status Register indicates the nature of

the interrupt, and the Interrupt Enable Register controls

which event produces an output on the IRQ pin.

An on-chip digital integrator provides direct interface to di/

dt current sensors such as Rogowski coils. T he digital

integrator eliminates the need for external analog integrator,

and this solution provides excellent long-term stability and

T he ADE7753 is available in 20-lead SSOP package.
