FEATURES Metering Features • 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 class 0.5S or class 1 poly-phase watt-hour meter or class 2 poly-phase var-hour meter. • Accuracy of ±0.1% for active energy and ±0.2% for reactive energy over the dynamic range of 6000:1. • Temperature coefficient is 6 ppm/ ℃ (typical) for on-chip refer- ence voltage. • Single-point calibration on each phase over the whole dynamic range for active energy; no calibration needed for reactive/ apparent energy. • ±1 ℃ (typical) temperature sensor accuracy. • Electrical parameters measurement: less than ±0.5% fiducial error for Vrms, Irms, mean active/ reactive/ apparent power, fre- quency, power factor and phase angle. • Active (forward/reverse), reactive (forward/reverse), apparent energy with independent energy registers. Active/ reactive/ apparent energy can be output by pulse or read through energy registers to adapt to different applications. • Programmable startup and no-load power threshold, special designed of startup and no-load circuits to eliminate crosstalk among phases achieving better accuracy especially at low power conditions. • Dedicated ADC and different gains for phase A/B/C and Neutral line current sampling circuits. Current sampled over current transformer (CT) or Rogowski coil (di/dt coil); phase A/B/C volt- age sampled over resistor divider network or potential trans- former (PT). • Programmable power modes: Normal mode (N mode), Idle mode (I mode), Detection mode (D mode) and Partial Measure- ment mode (M mode). • Fundamental (CF3, 0.2%) and harmonic (CF4, 1%) active energy with dedicated energy and power registers. • Total Harmonic Distortion (THD) and Discrete Fourier Transform (DFT) functions for 2 ~ 32 order harmonic component. THD and DFT results available in SPI accessible registers. Both voltage and current of all phases processed within the same time period. • Event detection: sag, phase loss, reverse voltage/ current phase sequence, reverse flow, calculated neutral line current INC over- current sampled neutral line current INS overcurrent and THD+N over-threshold. Other Features • 3.3V single power supply. Operating voltage range: 2.8V~3.6V. Metering accuracy guaranteed within 3.0V~3.6V. • Four-wire SPI interface with Direct Memory Access (DMA) mode to stream out 7-channel ADC raw data. • Parameter diagnosis function and programmable interrupt output of the IRQ interrupt signals and the WarnOut signal. • Programmable voltage sag detection and zero-crossing output. • CF1/CF2/CF3/CF4 output active/ reactive/ apparent energy pulses and fundamental/ harmonic energy pulses respectively. • Crystal oscillator frequency: 16.384 MHz. On-chip two capacitors and no need of external capacitors. • TQFP48 package. • Operating temperature: -40 ℃ ~ +85 ℃ . APPLICATION • Poly-phase energy meters of class 0.5S and class 1 which are used in three-phase four-wire (3P4W, Y0) or three-phase three- wire (3P3W, Y or ∆) systems. • Data Acquisition Terminal. • Power monitoring instruments which need to measure voltage, current, THD, DFT, mean power, etc. GENERAL DESCRIPTION The 90E36 is a poly-phase high performance wide-dynamic range metering IC. The 90E36 incorporates 7 independent 2nd order sigma- delta ADCs, which could be employed in three voltage channels (phase A, B and C) and four current channels (phase A, B, C and neutral line) in a typical three-phase four-wire system. The 90E36 has an embedded DSP which executes calculation of active energy, reactive energy, apparent energy, fundamental and har- monic active energy over ADC signal and on-chip reference voltage. The DSP also calculates measurement parameters such as voltage and current RMS value as well as mean active/reactive/apparent power. A four-wire SPI interface is provided between the 90E36 and the external microcontroller. In addition, DMA mode can be used for 7-chan- nel ADC raw data access, offering more flexibility in system application. The 90E36 is suitable for poly-phase multi-function meters which could measure active/reactive/apparent energy and fundamental/har- monic energy either through four independent energy pulse outputs CF1/CF2/CF3/CF4 or through the corresponding registers. With the on-chip THD and DFT engine, all phases' THD and DFT results can be directly accessed through related registers, thus simplify- ing hardware design in Data Acquisition Terminals. IDT's proprietary ADC and auto-temperature compensation technol- ogy for reference voltage ensure the 90E36's long-term stability over variations in grid and ambient environment conditions. |
