CS5462-ISZR

Overview

The CS5462-ISZR is a single-phase energy metering integrated circuit manufactured by Cirrus Logic. It operates within a supply voltage range of 2.4 V to 2.6 V and consumes a typical operating current of 25 nA. The device features an SOIC-8 surface-mount package and supports an output current capability of 1 uA. It is designed for low-cost power and energy measurement applications with pulse output functionality. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated or high-efficiency metering systems
• Integrated single-phase energy metering with direct pulse output interface
• Compact surface-mount packaging for space-constrained PCB layouts

Applications

• Residential electricity metering systems
• Industrial power monitoring equipment
• Low-power smart grid sensors

Procurement Notes

Verify the specific suffix ISZR against official datasheets to confirm tape-and-reel packaging configuration. Confirm end-of-life status as distributors may list obsolete stock. Validate RoHS compliance documentation prior to integration into regulated assemblies.

Selection Notes

Select this component for applications requiring minimal quiescent current in single-phase environments. Ensure the system design accommodates the narrow 2.4 V to 2.6 V supply voltage window. Compare against higher-voltage variants if system rails exceed 2.6 V.

Part Context

This part belongs to the Cirrus Logic CS546x family of analog-to-digital converters optimized for utility metering. It complements other models like the CS5461 and CS5463, offering specialized low-power characteristics distinct from the broader family's standard operating ranges.

Replacement Considerations

Publicly confirmed substitutes include CS5462-ISZ. Verify pin compatibility and electrical specifications before substitution.
