FEATURES

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

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

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

and other 3-phase services

Supplies total (fundamental and harmonic) active, reactive,

and apparent energy and fundamental active/reactive

energy on each phase and on the overall system

0.1% error (typical) in active and reactive energy over a

dynamic range of 1000 to 1 at TA = 25°C

0.2% error (typical) in active and reactive energy over a

dynamic range of 3000 to 1 at TA = 25°C

Averaged rms measurements available in low ripple rms

registers

Supports current transformer and di/dt current sensors

Dedicated ADC channel for neutral current input

Estimated neutral current measurement by calculating the

rms of the sum of the phase currents in all 3 phases

0.1% error (typical) in voltage and current rms over a

dynamic range of 1000 to 1 at TA = 25°C

Supplies sampled waveform data on all 3 phases and on

neutral current

Selectable no load thresholds for total and fundamental

active and reactive powers, as well as for apparent powers

Highly accurate low power battery mode phase current

monitoring for antitampering detection

Battery supply input for missing neutral operation

Phase angle measurements in current and voltage channels

Calibration frequency (CF) output directly drives LED and

opto-isolators

Reference: 1.2 V (drift of ±5 ppm/°C typical) with external

overdrive capability

Single 3.3 V supply

40-lead, Pb-free lead frame chip scale package (LFCSP)

Operating temperature: −40°C to +85°C

Flexible I2C, SPI, and HSDC serial interfaces
