SA9110A
MONOCHIP THREE PHASE BIDIRECTIONAL
KILOWATT HOUR METERING IC
FEATURES
n Performs bidirectional energy meter-
ing and directly drives a LCD with 7
digits plus announciators
n 4 externally selectable on-chip tariff
registers
n An additional total energy register
n Meets the IEC 521/1036 Specification
requirements for Class 1 AC Watt hour
meters
n Optical interface for electronic reading
according to IEC1107 Mode D
DESCRIPTION
The SAMES SA9110A Three Phase bidi-
rectional energy metering integrated cir-
cuit has an integrated Liquid Crystal Dis-
play (LCD) driver for a 7 digit (7 segment)
display as well as 4 multiple tariff registers.
The SA9110A performs the active power
calculation.
The method of calculation takes the power
factor into account.
The measured energy is displayed in kilo
Watt hours (kWh). The SA9110A is capa-
ble of driving a display having a resolution
of 1/10 kWh.
This innovative universal energy metering
integrated circuit is ideally suited for en-
ergy measurement in three phase sys-
tems.
The SA9110A integrated circuit is avail-
able in a 68 pin plastic leaded chip carrier
(PLCC-68) package type.
