1. General Description
The ATT7053BU is a single-phase multi-function energy measurement chip with SPI serial interface .
Wide supply voltage operation :4.5V-5.5V.
Recommends 6MHz crystal oscillator.
Feature：
z Three 19 bit sigma-delta ADCs
z Over Dynamic range of 3000:1.
z Supply active power and reactive power of two channels simultaneously.
z Support active, reactive, apparent power measurement and energy pulse output.
z Simultaneously supply RMS measurement of three ADC channels, and the frequency of voltage channel
z Support SPI communication manner
z Support zero-crossing interrupt, sampling interrupt, energy pulse interrupt and calibration interrupt.
z Less than 4.5 mA current supply in normal mode, less than 2mA current supply in burglar-proof electricity
and voltage-depreciation mode.
z Support the power supply monitoring and battery monitoring.
