1 / 54 page  1 Copyright © Cirrus Logic, Inc. 2004 (All Rights Reserved) Cirrus Logic, Inc. http://www.cirrus.com CS5460A Single Phase Bi-Directional Power/Energy IC Features Energy Data Linearity: ±0.1% of Reading over 1000:1 Dynamic Range. On-Chip Functions: (Real) Energy, I ∗ V, IRMS and VRMS, Energy-to-Pulse Conversion Smart “Auto-Boot” Mode from Serial EEPROM Enables Use without MCU. AC or DC System Calibration Mechanical Counter/Stepper Motor Driver Meets Accuracy Spec for IEC 687/1036, JIS Typical Power Consumption <12 mW Interface Optimized for Shunt Sensor V vs. I Phase Compensation Ground-Referenced Signals with Single Supply On-chip 2.5 V Reference (MAX 60 ppm/°C drift) Simple Three-Wire Digital Serial Interface Watch Dog Timer Power Supply Monitor Power Supply Configurations VA+ = +5 V; VA- = 0 V; VD+ = +3.3 V to +5 V Description The CS5460A is a highly integrated power mea- surement solution which combines two ∆Σ Analog-to-Digital Converters (ADCs), high speed power calculation functions, and a serial interface on a single chip. It is designed to accurately mea- sure and calculate: Real (True) Energy, Instantaneous Power, IRMS, and VRMS for single phase 2- or 3-wire power metering applications. The CS5460A interfaces to a low-cost shunt resis- tor or transformer to measure current, and to a resistive divider or potential transformer to mea- sure voltage. The CS5460A features a bi-directional serial interface for communication with a micro-controller and a pulse output engine for which the average pulse frequency is propor- tional to the real power. The CS5460A has on-chip functionality to facilitate AC or DC system-level calibration. The “Auto-Boot” feature allows the CS5460A to function ‘stand-alone’ and to initialize itself on sys- tem power-up. In Auto-Boot Mode, the CS5460A reads the calibration data and start-up instructions from an external EEPROM. In this mode, the CS5460A can operate without a microcontroller, in order to lower the total bill-of-materials cost.
