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 watt-hour 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 refer-
ence voltage
Single-point calibration over a dynamic range of 5000:1 for
active energy; no calibration needed for reactive energy.
Energy Meter Constant doubling at low current to save verifica-
tion time.
Electrical parameters measurement: less than ±0.5% fiducial
error for Vrms, Irms, mean active/ reactive/ apparent power, fre-
quency, power factor and phase angle.
Forward/ reverse active/ reactive energy with independent
energy registers. Active/ reactive energy can be output by pulse
or read through energy registers to adapt to different applica-
tions.
Programmable startup and no-load power threshold.
Dedicated ADC and different gains for L line and N line current
sampling circuits. Current sampled over shunt resistor or current
transformer (CT); voltage sampled over resistor divider network
or potential transformer (PT).
Programmable L line and N line metering modes: anti-tampering
mode (larger power), L line mode (fixed L line), L+N mode (appli-
cable for single-phase three-wire system) and flexible mode
(configure through register).
Programmable L line and N line power difference threshold in
anti-tampering mode.
Other Features
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.
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.
Channel input range
- Voltage channel (when gain is '1'): 120
Vrms~600mVrms.
- L line current channel (when gain is '24'): 5
Vrms~25mVrms.
- N line current channel (when gain is '1'): 120
Vrms~600mVrms.
Programmable L line current gain: 1, 4, 8, 16, 24; Programmable
N line gain: 1, 2, 4.
Support L line and N line offset compensation.
CF1 and CF2 output active and reactive energy pulses respec-
tively which can be used for calibration or energy accumulation.
Crystal oscillator frequency: 8.192 MHz. On-chip 10pF capaci-
tors and no need of external capacitors.
Green SSOP28 package.
Operating temperature: -40 ℃ ~ +85 ℃ .
APPLICATION
The 90E21/22/23/24 series are used for active and reactive
energy metering for single-phase two-wire, single-phase three-
wire or anti-tampering energy meters. With the measurement
function, the 90E21/22/23/24 series can also be used in power
instruments which need to measure voltage, current, etc.
DESCRIPTION
The 90E21/22/23/24 series are high-performance wide-span energy
metering chips. IDT's proprietary ADC and DSP technology ensure the
chips' long-term stability over variations in grid and ambient environmen-
tal conditions.
90E21/22/23/24 are all of green SSOP28 package with the same pin
alignment. In this datasheet, all reactive energy metering parts are only
applicable for the 90E22/24, and all N line metering and measurement
parts are only applicable for the 90E23/24.
