Overview

The CS5467-ISZ IC for digital power meters and energy measurement applications is designed for market-specific demands within Japan. It is an integrated power measurement device which combines three Delta Sigma analog-to-digital converters, power calculation engine, energy-to-frequency converter and a serial interface into a single integrated circuit. It accurately measures instantaneous current and voltage and calculates VRMS, IRMS, instantaneous power and average power (active/reactive/apparent) for high-performance power measurement applications. In addition, the CS5467-ISZ features two current channels and two voltage channels for simultaneous two-phase measurements. This configuration is popular in network meters and commercial three-phase metering applications throughout the world.The CS5467-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 CS5467-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.
