CS5463K-ISZ

Overview

The CS5463K-ISZ is a single-phase power and energy metering integrated circuit manufactured by Cirrus Logic Inc. It operates within a supply voltage range of 3.135 V to 5.25 V, with a typical supply current of 2.9 mA. The device features an input impedance of 30 kOhm and achieves a measurement error of 0.1%. It supports I/O high voltages of 4 V and low voltages of 0.4 V. Packaged in a 24-SSOP format (5.30 mm width), it functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides high-accuracy single-phase energy and power measurement capabilities
• Integrates digital signal processing for precise metering applications
• Supports surface mount installation in compact 24-SSOP packages

Applications

• Single-phase electricity metering systems
• Power monitoring equipment
• Energy management devices

Procurement Notes

Verify the specific suffix 'K' against official datasheets to confirm package or temperature grade variations. Confirm RoHS3 compliance status as indicated in distributor records. Check for Last Time Buy notifications due to potential supply constraints. Ensure compatibility with 3.135 V to 5.25 V supply rails during integration.

Selection Notes

Select this component for single-phase metering designs requiring 0.1% accuracy. Verify that the 24-SSOP footprint fits the PCB layout. Ensure the system operates within the specified -40°C to 85°C ambient temperature range. Confirm interface voltage levels match the 4 V high / 0.4 V low specifications.
