The ATM90E25-YU-R from Microchip Technology is a sophisticated integrated circuit designed for active energy metering in single-phase applications. It supports both single-phase two-wire (1P2W) and single-phase three-wire (1P3W) systems, as well as anti-tampering configurations.
Key metering features include an accuracy of 0.1% for active energy over a dynamic range of 5000:1 and less than ±0.5% fiducial error for electrical parameters like Vrms, Irms, and frequency. The device operates on a single 3.3V power supply with a voltage range of 2.8V to 3.6V, with metering accuracy guaranteed between 3.0V and 3.6V. It is compatible with 5V digital inputs.
This IC is housed in a compact 28-SSOP package, suitable for surface mounting. It operates reliably within an extended temperature range of -40°C to +85°C, making it suitable for various environmental conditions. The ATM90E25-YU-R also features a four-wire SPI or simplified three-wire SPI interface for communication and parameter configuration.
Applications for the ATM90E25-YU-R include single-phase watt-hour meters and power instruments requiring precise voltage and current measurements. Its design facilitates compliance with IEC62052-11 and IEC62053-21 standards.
