MONOCHIP SINGLE PHASE BIDIRECTIONAL
KILOWATT HOUR METERING IC
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.
PIN CONNECTIONS
n
Optical interface for electronic reading
according to IEC1107 Mode D
Pulse output for calibration
Power consumption rating below 40mW
Adaptable to different types of current
sensors
Operates over a wide temperature
range
Precision voltage reference on-chip
Protected against ESD
