ADI ADE7953ACPZ

0.1%3 В ~ 3,6 ВОднофазный

Overview

The ADE7953ACPZ is a high accuracy electrical energy measurementIC intended for single phase applications. It measures line voltageand current and calculates active, reactive, and apparent energy,as well as instantaneous rms voltage and current.

The ADE7953ACPZ provides access to on-chip meter registers via avariety of communication interfaces including SPI, I2C, and UART.Two configurable low jitter pulse output pins provide outputs thatare proportional to active, reactive, or apparent energy, as well ascurrent and voltage rms. A full range of power quality informationsuch as overcurrent, overvoltage, peak, and sag detection areaccessible via the external IRQ pin. Independent active, reactive,and apparent no-load detections are included to prevent “metercreep.” Dedicated reverse power (REVP), zero-crossing voltage(ZX), and zero-crossing current (ZX_I) pins are also provided. TheADE7953ACPZ energy metering IC operates from a 3.3 V supply voltageand is available in a 28-lead LFCSP package.
