GENERAL DESCRIPTION
The ADE7953 is a high accuracy electrical energy measurement
IC intended for single phase applications. It measures line voltage
and current and calculates active, reactive, and apparent energy,
The device incorporates three Σ-Δ ADCs with a high accuracy
energy measurement core. The second input channel simulta-
neously measures neutral current and enables tamper detection
and neutral current billing. The additional channel incorporates
a complete signal path that allows a full range of measurements.
Each input channel supports independent and flexible gain stages,
making the device suitable for use with a variety of current sensors
such as current transformers (CTs) and low value shunt resistors.
Two on-chip integrators facilitate the use of Rogowski coil sensors.
The ADE7953 provides access to on-chip meter registers via a
variety of communication interfaces including SPI, I 2 C, and UART.
Two configurable low jitter pulse output pins provide outputs that
are proportional to active, reactive, or apparent energy, as well as
current and voltage rms. A full range of power quality information
such as overcurrent, overvoltage, peak, and sag detection are
accessible via the external IRQ pin. Independent active, reactive,
and apparent no-load detections are included to prevent “meter
creep.” Dedicated reverse power (REVP), zero-crossing voltage
(ZX), and zero-crossing current (ZX_I) pins are also provided. The
ADE7953 energy metering IC operates from a 3.3 V supply voltage
and is available in a 28-lead LFCSP package.
as well as instantaneous rms voltage and current.
