1 / 46 page  Copyright Cirrus Logic, Inc. 2011 (All Rights Reserved) http://www.cirrus.com CS5463 Single Phase, Bi-directional Power/Energy IC Features Energy Data Linearity: ±0.1% of Reading over 1000:1 Dynamic Range On-chip Functions: - Instantaneous Voltage, Current, and Power - IRMS and VRMS, Apparent, Reactive, and Active (Real) Power - Active Fundamental and Harmonic Power - Reactive Fundamental, Power Factor, and Line Frequency - Energy-to-pulse Conversion - System Calibrations and Phase Compensation - Temperature Sensor Meets accuracy spec for IEC, ANSI, JIS. Low Power Consumption Current Input Optimized for Sense Resistor. GND-referenced Signals with Single Supply On-chip 2.5 V Reference (25 ppm/°C typ) Power Supply Monitor Simple Three-wire Digital Serial Interface “Auto-boot” Mode from Serial E2PROM Power Supply Configurations: VA+ = +5 V; AGND = 0 V; VD+ = +3.3 V to +5 V Description The CS5463 is an integrated power measure- ment device which combines two analog-to-digital converters, power calculation engine, energy-to-frequency converter, and a serial interface on a single chip. It is designed to accurately measure instantaneous current and voltage, and calculate VRMS, IRMS, instanta- neous power, apparent power, active power, and reactive power for single-phase, 2- or 3-wire power metering applications. The CS5463 is optimized to interface to shunt re- sistors or current transformers for current measurement, and to resistive dividers or poten- tial transformers for voltage measurement. The CS5463 features a bi-directional serial inter- face for communication with a processor and a programmable energy-to-pulse output function. Additional features include on-chip functionality to facilitate system-level calibration, temperature sensor, voltage sag detection, and phase compensation. ORDERING INFORMATION: See Page 45.
