Enhanced Poly-Phase High-Performance Wide-Span

Energy Metering IC

DATASHEET

FEATURES

Metering Features

• Metering features fully in compliance with the requirements of IEC62052-11,

IEC62053-22 and IEC62053-23, ANSI C12.1 and ANSI C12.20; applicable in poly-

phase class 0.2S, 0.5S or class 1 watt-hour meter or class 2 var-hour meter.

• Accuracy of ±0.1% for active energy and ±0.2% for reactive energy over a

dynamic range of 6000:1.

• Temperature coefficient is 6 ppm/ ℃ (typ.) for on-chip reference voltage. Automati-

cally temperature compensated.

• Single-point calibration on each phase over the whole dynamic range for active

energy; no calibration needed for reactive/ apparent energy.

• ±1 ℃ (typ.) temperature sensor accuracy.

• Flexible piece-wise non-linearity compensation: three current (RMS value)-based

segments with two programmable thresholds for each phase. Independent gain and

phase angle compensation for each segment.

• Electrical parameters measurement: less than ±0.5% fiducial error for Vrms, Irms,

mean active/ reactive/ apparent power, frequency, power factor and phase angle.

• Active (forward/reverse), reactive (forward/reverse), apparent energy with indepen-

dent energy registers.

• Programmable startup and no-load power thresholds.

• 6 dedicated ADCs for phase A/B/C current and voltage sampling circuits. Current

sampled over Current Transformer (CT) or Rogowski coil (di/dt coil); voltage sam-

pled over resistor divider network.

• Programmable power modes: Normal, Idle, Detection and Partial Measurement

mode.

• Fundamental (0.2%) and harmonic (1%) active energy with dedicated energy /

power registers and independent energy outputs.

• Current and voltage instantaneous signal monitoring.

• Enhanced event detection: sag, over voltage, phase loss, over current, reverse V/I

phase sequence, calculated neutral line current I

over-current and frequency

upper and lower threshold.

Other Features

• 3.3V single power supply. Operating voltage range: 2.8V~3.6V. Metering accuracy

guaranteed within 3.0V~3.6V.

• Four-wire SPI interface.

• Programmable voltage sag detection and zero-crossing output.

• Crystal oscillator frequency: 16.384MHz. On-chip two capacitors and no need of

external capacitors.

• Lower power consumption. I=13mA (typ.) in Normal mode.

• TQFP48 package.

• Operating temperature: -40 ℃ ~ +85 ℃ .
