Poly Phase Multifunction Energy Metering IC

with per Phase Active and Reactive Powers

Preliminary Technical Data

ADE7858

processing required to perform total (fundamental and

FEATURES

harmonic) active, reactive and apparent energy measurement,

and rms calculations. A fixed function digital signal processor

Highly accurate; supports EN 50470-1, EN 50470-3,

IEC 62053-21, IEC 62053-22 and IEC 62053-23

Compatible with 3-phase, 3 or 4 wire (delta or wye) and

other 3-phase services

Supplies total (fundamental and harmonic) active/reactive/

apparent energy on each phase and on the overall system

Less than 0.1% error in active and reactive energy over a

dynamic range of 1000 to 1 at 25°C

Less than 0.2% error in active and reactive energy over a

dynamic range of 3000 to 1 at 25°C

Supports current transformer and di/dt current sensors

Less than 0.1% error in voltage and current rms over a

dynamic range of 1000 to 1 at 25°C

Supplies sampled waveform data on all 3 phases

Selectable No-load threshold level for total active, reactive

and apparent powers

Phase angle measurements in both current and voltage

channels with max 0.3° error

Wide supply voltage operation 2.4 to 3.7V

Reference 1.2 V (drift 10 ppm/°C typ) with external

overdrive capability

(DSP) executes this signal processing.

The ADE7858 is suitable to measure active, reactive, and

apparent energy in various 3-phase configurations, such as

WYE or DELTA services, with both three and four wires. The

ADE7858 provides system calibration features for each phase,

that is, rms offset correction, phase calibration, and gain

calibration. The CF1, CF2 and CF3 logic outputs provide a wide

choice of power information: total active/reactive/apparent

power or sum of current rms values.

The ADE7858 has waveform sample registers that allow access

to all ADC outputs. The device also incorporates power quality

measurements such as short duration low or high voltage

detections, short duration high current variations, line voltage

period measurement and angles between phase voltages and

currents. Two serial interfaces can be used to communicate with

the ADE7858: SPI or I²C while a dedicated high speed interface,

HSDC (High Speed Data Capture) port, can be used in

conjunction with I²C to provide access to the ADC outputs and

real time power information. The ADE7858 has also two

Single 3.3 V supply

interrupt request pins, IRQ0 and IRQ1, to indicate that an

40-Lead Frame Chip Scale (LFCSP) Lead Free Package

Operating temperature -40° to 85°C

Flexible I²C, SPI®, HSDC serial interfaces

enabled interrupt event has occurred.

The ADE7858 is available in 40-lead LFCSP lead free package.

GENERAL DESCRIPTION

The ADE7858¹is a high accuracy, 3-phase electrical energy

measurement IC with serial interfaces and three flexible pulse

outputs. The ADE7858 incorporates second-order Σ-Δ ADCs, a

digital integrator, reference circuitry, and all the signal
