Cirrus Logic CS5463-ISZ Energy Meter IC
The Cirrus Logic CS5463-ISZ Energy Meter IC is designed for single-phase electrical energy measurement and power monitoring applications. It integrates the measurement functions required to monitor voltage and current and calculate important electrical parameters, reducing the amount of external circuitry needed in an energy-meter design.
The device is suitable for applications requiring measurement of voltage, current, power, energy, power factor, and line frequency. Its metering architecture is intended for use with appropriate voltage and current sensing circuits, allowing it to be incorporated into electronic electricity meters and embedded power-monitoring equipment.
The CS5463 family provides a serial interface for communication with a host microcontroller, allowing measured data and configuration parameters to be handled digitally. The IC also supports calibration functions to help compensate for measurement-system variations.
The CS5463-ISZ is supplied in a 24-pin SSOP surface-mount package, making it suitable for compact PCB designs. Distributor specifications list a 4.75V to 5.25V supply range, approximately 2.9mA supply current, -40°C to +85°C operating temperature, and 0.1% measurement error.
Availability note: The CS5463-ISZ is currently listed as obsolete and no longer manufactured by DigiKey. If you are sourcing this exact part in Pakistan, stock should be verified carefully. DigiKey identifies CS5463K-ISZ as the manufacturer’s recommended substitute.
