The ATM90E32AS-AU-Y from Microchip Technology is an enhanced poly-phase, high-performance energy metering IC designed for precision measurement in poly-phase systems. It offers metering features fully compliant with IEC62052-11, IEC62053-22, IEC62053-23, ANSI C12.1, and ANSI C12.20 standards, suitable for class 0.2S, 0.5S, or class 1 watt-hour meters.
This IC boasts an accuracy of ±0.1% for active energy and ±0.2% for reactive energy over a dynamic range of 6000:1. It supports single-point calibration for active energy and provides electrical parameter measurements with less than ±0.5% fiducial error for Vrms, Irms, mean active/reactive/apparent power, frequency, power factor, and phase angle. The device operates with a 3.3V single power supply, with metering accuracy guaranteed within 3.0V to 3.6V.
Designed for demanding applications, the ATM90E32AS-AU-Y incorporates 6 dedicated ADCs for phase A/B/C current and voltage sampling. It supports various power modes and enhanced event detection, including sag, overvoltage, phase loss, and overcurrent. The IC is housed in a 48-TQFP package, suitable for surface mounting, and operates across a wide temperature range of -40°C to +85°C.
