SA9122E

SINGLE PHASE UNIDIRECTIONAL POWER/ENERGY

METERING IC WITH SEPERATE 64 SEGMENT LCD DRIVER

FEATURES

sames

Performs unidirectional power and

energy measurement

On-chip 64 segment LCD driver

Meets the IEC 521/1036 Specification

requirements for Class 1 AC Watt hour

meters

Total power consumption rating below

25 mW

Adaptable to different types of current

sensors

Operates over a wide temperature

range

Different pulse rate options available

for power information

LCD data input via a serial interface

DESCRIPTION

The SAMES SA9122E Single Phase

unidirectional active Power/Energy metering

integrated circuit includes a seperate on-

chip 64 segment Liquid Crystal Display driver.

The power/energy metering circuit generates

a pulse rate output, proportional to the power

consumption, while the LCD driver is

programmable via a serial interface.

The method of power calculation takes the

power factor into account. Energy consump-

tion is determined by the power measurement

being integrated over time.

The LCD driver is capable of driving 8 decimal

digits (7 segment) and 8 announciators on a

4 track multiplexed backplane display.

This innovative combination energy metering/

LCD display driver integrated circuit has

been designed to provide meter designers

with flexibility in the choice of the µ-controller

employed, and is ideally suited for applica-

tions such as residential municipal metering

and factory energy metering and control.

The SA9122E integrated circuit is available

in both 40 pin dual-in-line plastic (DIP-40), as

well as 44 pin plastic leaded chip carrier

(PLCC-44) package types.
