• Contains a fixed-function digital signal processor that performs real-time calculation of active, reactive, and apparent power values.
• Provides programmable pulse outputs to indicate total or fundamental power quantities without microcontroller intervention.

Energy Metering Applications

• Polyphase energy metering systems
• Power quality monitoring equipment
• Solar inverter control units

Energy Metering Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical specifications. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure the selected package variant matches the required thermal and mechanical constraints for the target application design.

Energy Metering Selection Notes

Select this component when designing systems requiring high-accuracy polyphase measurements with minimal external processing overhead. Evaluate the integration of internal DSP functions against the need for flexible harmonic analysis. Consider the physical footprint requirements of the 40-pin LFCSP package during the PCB layout phase.
