DESCRIPTION

This innovative universal single phase power/energy

metering integrated circuit is ideally suited for energy

calculations in applications such as residential municipal

metering and factory energy metering and control.

The SA9602E is an enhancement of the SA9102E, as no

external capacitors are required for the A/D converters.

The SA9602E single phase unidirectional power/energy

metering integrated circuit generates a pulse rate output, the

frequency of which is proportional to the power consumption.

The SA9602E performs the calculation for active power. The

method of calculation takes the power factor into account.

Energy consumption can be determined by the power

measurement being integrated over time.

The SA9602E integrated circuit is available in a 20 pin small

outline (SOIC20) RoHS compliant package.
