The Microchip Technology ATM90E26-YU-R is a sophisticated integrated circuit designed for single-phase active and reactive energy metering applications. It fully complies with IEC62052-11, IEC62053-21, and IEC62053-23 standards, making it suitable for class 1 or class 2 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 5000:1. It supports a wide operating voltage range of 2.8V to 3.6V, with metering accuracy guaranteed within 3.0V to 3.6V. Electrical parameters like Vrms, Irms, power, frequency, and power factor are measured with a fiducial error of less than ±0.5%.
The ATM90E26-YU-R features flexible metering modes, including anti-tampering, L line, L+N, and flexible configurations, adaptable through registers. It supports sampling over shunt resistors or current transformers (CT) and voltage over resistor divider networks or potential transformers (PT). The device includes selectable UART and SPI interfaces and operates within a temperature range of -40°C to +85°C.
Packaged in a compact 28-SSOP, this energy metering IC is ideal for single-phase two-wire (1P2W) and single-phase three-wire (1P3W) systems. Its robust feature set and high accuracy make it a reliable choice for modern energy metering solutions.
