CS5463-ISZ

Overview

The CS5463-ISZ is a single-phase, bi-directional power and energy measurement integrated circuit manufactured by Cirrus Logic. It operates within a supply voltage range of 4.75 V to 5.25 V and draws a typical supply current of 2.9 mA. The device features an input impedance of 30 kΩ and achieves a measurement error of 0.1%. It utilizes a 24-SSOP package with dimensions of 0.209 inches (5.30 mm) in width. The component supports I/O high levels of 0.8 V and low levels of 0.2 V. It is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides single-phase bi-directional power and energy measurement capabilities
• Integrates high-precision analog-to-digital conversion for metering applications
• Supports digital interface communication for data retrieval and configuration

Applications

• Single-phase electricity meters
• Power quality monitoring systems
• Energy management devices

Procurement Notes

Verify the specific suffix designation carefully, as variations such as ISZR indicate tape-and-reel packaging while ISZ denotes tube packaging. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary due to production lifecycle changes. Ensure the source channel guarantees authenticity to avoid counterfeit components.

Selection Notes

Select this component for applications requiring accurate single-phase energy measurement with bi-directional flow capability. Consider the 24-SSOP package constraints and the 4.75 V to 5.25 V supply requirement during board design. Evaluate the need for external calibration if the specified 0.1% error meets system accuracy requirements. Verify compatibility with existing SPI or UART interfaces used in the target design.

Part Context

The CS5463 belongs to the Cirrus Logic CS546x family of power management ICs specialized for energy metering. This series includes variants like the CS5460A and CS5461A, which share similar functional architectures but may differ in pin counts or specific feature sets. The CS5463-ISZ represents a specific package variant within this established line of single-phase metering solutions.

Replacement Considerations
