产品信息

ATM90E32AS-AU-R

模拟前端 – AFE 48-TQFP, IND TEMP 1.8V/3V

Enhanced Poly-Phase High-Performance Wide-Span Energy Metering IC


FEATURES

Metering Features  ATM90E32AS-AU-R

• 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 polyphase 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. Automatically 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.


Other Features ATM90E32AS-AU-R

• 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 ℃ .


APPLICATION ATM90E32AS-AU-R

• Poly-phase energy meters of class 0.2S, 0.5S and class 1 which are used in three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems.

• Power monitoring instruments which need to measure voltage, current, mean power, etc.
