Single Phase Bidirectional Power/Energy

Metering IC with Instantaneous Pulse Output

SA2002H

FEATURES



Total power consumption rating below 25mW

Adaptable to different types of current sensors

Operates over a wide temperature range

Precision voltage reference on-chip

Precision oscillator on-chip



Functionally compatible with the SA9602H with reduced

external components



Bidirectional power and energy measurement

Meets the IEC 521/1036 Specification requirements for

Class 1 AC Watt hour meters



Protected against ESD

DESCRIPTION

The SA2002H is an enhancement of the SA9602H, as the

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.

circuit contains the oscillator on chip.

The SA2002H single phase bidirectional power/energy

metering integrated circuit generates a pulse rate output with

a frequency proportional to the power consumption.

The SA2002H integrated circuit is available in 8 pin dual inline

(PDIP8) as well as 20 pin and 16 pin small outline (SOIC20,

SOIC16) RoHS compliant package options.

The SA2002H performs a 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.
