CS5464K-ISZ

Overview

The CS5464K-ISZ is a three-channel, single-phase power and energy integrated circuit manufactured by Cirrus Logic Inc. It measures line voltage and current to calculate active, reactive, and apparent power, energy, power factor, and RMS values. The device operates within a supply voltage range of 4.75 V to 5.25 V with a typical supply current of 2.9 mA. It features an input impedance of 30 kOhm and maintains a measurement error of 0.1%. The component is housed in a 28-SSOP package (0.209 inch width) and supports surface mount installation. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Performs comprehensive single-phase energy metering including active, reactive, and apparent power calculations
• Provides direct measurement of voltage and current effective values alongside power factor determination
• Integrates three independent measurement channels for multi-point monitoring capabilities

Applications

• Single-phase residential and commercial electricity meters
• Power quality monitoring systems requiring precise energy data
• Smart grid infrastructure components for load management

Procurement Notes

Verify the specific suffix 'K' against official Cirrus Logic documentation to confirm any distinct manufacturing or compliance variations compared to standard variants. Confirm current availability status as distribution channels may list obsolete or end-of-life stock. Ensure the 28-SSOP package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing single-phase metering solutions requiring high accuracy and integrated power calculation. The 28-SSOP package offers a compact form factor suitable for space-constrained applications. Consider the 30 kOhm input impedance for sensor interface compatibility. Evaluate the -40°C to +85°C operating range against your environmental conditions to ensure reliable performance.

Part Context

This part belongs to the CS546x family of energy metering ICs from Cirrus Logic. It serves as a specialized solution for single-phase applications, distinguishing itself from multi-phase counterparts like the CS5463. The K suffix typically denotes specific packaging or compliance attributes within the manufacturer's lineup, differentiating it from other pin-compatible variants such as the CS5464-ISZ.
