CS5461A-IS

CS5461A-IS概述

Other Power Management Single-Phase Bi-Dir Power/Energy IC

Description

The CS5461A is an integrated power measure ment device which combines two  ∆Σ 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, instantaneous power, apparent power, and active power for single-phase, 2- or3-wire power metering applications.

Features

• Energy Data Linearity: ±0.1% of Reading over 1000:1 Dynamic Range

• On-chip Functions:

  - Instantaneous Voltage, Current, and Power

  - IRMSand VRMS, Apparent and Active Real Pow

  - Energy-to-pulse Conversion for Mechanical Counter/Stepper Motor Drive

  - System Calibrations and Phase Compensation

  - Temperature Sensor

\- Voltage Sag Detect

• 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
