ATM90E26-YU-R

Single-Phase High-Performance Wide-Span  Energy Metering IC

模拟前端 – AFE 28-SSOP 1.8V/3V28- SSOP 1.8V/3V

DESCRIPTION ATM90E26-YU-R

The M90E26 is a high-performance wide-span energy metering chip. The ADC and DSP technology ensure the chip's longterm stability over variations in grid and ambient environmental conditions.

Other Features ATM90E26-YU-R

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

guaranteed within 3.0V~3.6V. 5V compatible for digital input.

• Built-in hysteresis for power-on reset.

• Selectable UART interface and SPI interface (four-wire SPI interface or simplified

three-wire SPI interface with fixed 24 cycles for all registers operation).

• Parameter diagnosis function and programmable interrupt output of the IRQ interrupt

signal and the WarnOut signal.

• Programmable voltage sag detection and zero-crossing output.

FEATURES

Metering Features

• Metering features fully in compliance with the requirements of IEC62052-11, IEC62053-21 and IEC62053-23; applicable in class 1 or class 2 single-phase watthour meter or class 2 single-phase var-hour meter.

• Accuracy of 0.1% for active energy and 0.2% for reactive energy over a dynamic range of 5000:1.

• Temperature coefficient is 15 ppm/ ℃ (typical) for on-chip reference voltage

• Single-point calibration over a dynamic range of 5000:1 for active energy; no cali-bration needed for reactive energy.

• Energy Meter Constant doubling at low current to save verification time.

APPLICATION ATM90E26-YU-R

The M90E26 is used for active and reactive energy metering for single-phase two-wire (1P2W), single-phase three-wire (1P3W) or anti-tampering energy meters. With the measurement function, the M90E26 can also be used in power instruments which need to measure voltage, current, etc.
