CS5463-IS

Overview

The CS5463-IS is an integrated single-phase, bi-directional power and energy measurement IC manufactured by Cirrus Logic. It combines two delta-sigma analog-to-digital converters, a power calculation engine, an energy-to-frequency converter, and a serial interface on a single chip. The device is designed to accurately measure instantaneous current and voltage, calculating VRMS, IRMS, apparent power, active power, and reactive power for 2- or 3-wire metering applications.

Feature Summary

• Integrates dual delta-sigma ADCs with a dedicated power calculation engine
• Supports AC and DC calibration functions with phase compensation
• Provides high-speed calculation of multiple electrical parameters
• Features a serial interface for data connection and system control

Applications

• Single-phase electronic energy meters
• Bi-directional power monitoring systems
• Smart grid metering devices
• Industrial power quality analyzers

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and package integrity upon receipt. Check for specific ordering suffixes that may indicate tape-and-reel versus bulk packaging variations. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Selection Notes

Select this component for applications requiring high-accuracy single-phase energy measurement. Evaluate compatibility with existing serial communication protocols. Consider the need for external shunt or transformer interfaces for current sensing. Assess thermal performance within the specified operating temperature range during system design.

Part Context

The CS5463 series represents Cirrus Logic's solution for cost-effective, high-precision power metering. It replaces older discrete measurement architectures by integrating analog front-end conversion and digital signal processing. The IS variant typically denotes industrial temperature range specifications, aligning with broader family capabilities for robust utility-grade instrumentation.
