Overview

The CS5464-ISZ is an integrated power measurement device which combines three Delta-Sigma analog/digital converters (ADCs), power calculation engine, energy-to-frequency converter and a serial interface into a single integrated circuit. It is designed to accurately measure instantaneous current and voltage and calculates VRMS, IRMS, instantaneous power and average power (active/reactive/apparent) for high-performance power measurement applications.The CS5464-ISZ is optimized to interface to shunt resistors or current transformers for current measurement, and to resistive dividers or potential transformers for voltage measurement.The CS5464-ISZ features a bi-directional serial interface for communication with a processor and a programmable energy-to-pulse output function. It also has a tamper detection scheme that uses the larger of the active powers to register energy. Additional features include system-level calibration, temperature sensor, voltage sag, current fault detection and phase compensation.
