SA9109B
MONOCHIP SINGLE PHASE BIDIRECTIONAL
KILOWATT HOUR METERING IC
FEATURES
n Performs bidirectional energy meter-
ing and directly drives a LCD with 7
digits display plus announciators
n Programable method of energy addi-
tion
n Pin compatible with SAMES SA9109A
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
DESCRIPTION
The SAMES SA9109B Single 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 SA9109B performs the active power
calculation.
The method of calculation takes the power
factor into account.
Two methods of energy measurement are
available. One method results in energy
values which take the direction of energy
flow into account, a summation of signed
integers. The alternative method meas-
ures energy regardless of the direction of
energy flow, a summation of absolute
values. The required measurement
method may be selected when writing to
the RAM of the device.
n Optical interface for electronic reading
according to IEC1107 Mode D
n Pulse output for calibration
n Power consumption rating below 40mW
n Adaptable to different types of current
sensors
n Operates over a wide temperature
range
n Precision voltage reference on-chip
n Protected against ESD
