CS5460A-BSZ

Overview

The CS5460A-BSZ is a single-phase bidirectional power and energy monitoring integrated circuit manufactured by Cirrus Logic. It features dual 24-bit delta-sigma analog-to-digital converters with a sampling rate of 4000 samples per second. The device operates within an input voltage range of 2.4 V to 2.6 V for specific supply configurations, while supporting digital logic voltages from 3.3 V to 5.25 V. It provides a linear energy measurement accuracy of ±0.1% over a 1000:1 dynamic range. The component utilizes a 24-pin SSOP package and includes an internal 2.5 V reference voltage.

Feature Summary

• Integrates dual high-resolution delta-sigma analog-to-digital converters for simultaneous voltage and current sampling
• Includes a dedicated hardware engine for calculating active power and energy metrics
• Supports automatic initialization via external EEPROM for calibration data retrieval
• Provides phase compensation capabilities to correct timing errors between voltage and current signals

Applications

• Single-phase two-wire electronic energy meters
• Single-phase three-wire residential electricity meters
• Multi-user metering systems
• Industrial electrical data acquisition modules

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations may indicate differences in packaging or temperature ratings. Confirm RoHS compliance status through the specific datasheet revision. Ensure that the procurement channel provides traceable origin documents to guarantee component authenticity and prevent counterfeit risks.

Selection Notes

Evaluate the requirement for bidirectional power flow measurement if reverse energy consumption tracking is necessary. Consider the interface compatibility with the target microcontroller for SPI communication. Assess the need for internal reference stability versus external precision references based on system accuracy requirements and thermal environment constraints.

Part Context

This component belongs to the CS5460 family of energy metering ICs designed for cost-effective utility applications. It replaces older discrete measurement solutions by integrating signal conditioning, conversion, and calculation into a single semiconductor die. The design focuses on reducing bill-of-materials costs while maintaining industrial-grade accuracy standards.
