Programmable Single Phase Energy Metering
IC with Tamper Detection
SA9607P
FEATURES
s Provides direct interface to mechanical counters
s Calibration and setup stored on external EEPROM - no
trimpots required
s Monitors both Live and Neutral for tamper detection
s Performs bidirectional energy measurement
s Flexible programmable features
DESCRIPTION
The SAMES SA9607P is a single-phase bidirectional energy
metering integrated circuit. It provides a cost effective solution
for energy meters with electro-mechanical displays, such as
stepper motors and impulse counters.
Two current sensor inputs allow the measurement of energy
consumption on both the live and neutral lines.
Direction detection of energy flow as well as other common
tamper conditions are flagged.
The power consumption on both the live and neutral are
s Meets the IEC 521/1036 Specification for Class 1 AC Watt
hour meters
s Total power consumption rating below 25mW
s Adaptable to different types of sensors
s Operates over a wide temperature range
s Precision voltage reference on chip.
continuously measured and the larger of the two is selected
for energy metering.
The SA9607P drives the calibration LED and the
electromechanical counter directly.
The SA9607P does not require any external trim-pots. All
required calibration and configuration data is read from a
small external EEPROM.
The SA9607P integrated circuit is available in 20 pin dual-in-
line plastic (DIP-20) and small outline (SOIC-20) package
types.

INPUT SIGNALS
VREF
The VREF pin is the reference for the bias resistor and is the
recommended point for analog calibration. With a bias resistor
of 24koptimum conditions are set. Any changes to the bias
resistor will affect the output pulse rate quadratically (i.e.(R
= +5%,(f=10%).
Serial Data SDA
The SDA pin connects directly to the SDA pin of an external
EEPROM. The pin is used to transfer data between the
EEPROM to the SA9607P. An external pull up resistor in not
needed.
Serial Clock SCL
The SCL pin connects directly to the SCL of an external
EEPROM. The SCL output is used to strobe data at a rate of
50kHz out of the EEPROM. An external pull up resistor is not
needed.
Configuration CNF
A rising edge on the CNF pin, with DIRO high, will trigger a
register update from the external EEPROM. This feature may
be used during calibration to load updated register data in the
SA9607P. For normal operation of the SA9607P the CNF pin
should be connected to V .

OUTPUT SIGNALS
Motor output (MOP, MON)
The motor pulse width is programmable for 71ms and 142ms.
The MON pulse will follow the MOP pulse within the selected
pulse width time. This prevents that the motor armature is in
the wrong position after a power failure. Both MOP and MON
outputs are active high. One energy pulse is represented by a
MOP pulse followed by a MON pulse. The motor drive wave
forms are shown in figure 4.

LED output (LED)
Three options for the LED output pulse rate are available, 6400
and 3200 pulses per kWh, as well as a pulse rate of 1252
pulses per second at rated conditions. At 1252 pulses per
second tLED is 71µs, for the other options tLED is 10ms. The LED
output is active low as in figure 5.

Selected input indication (SEL1)
The SA9607P continuously compares the power consumptions
on both channel 1 and channel 2 inputs. The larger of the two
measurements are used for pulse output generation. The
SEL1 output pin indicates which channel is currently being
used for the pulse output.

Value Description
0 Current Channel 1 selected (IIN1 / IIP1)
1 Current Channel 2 selected (IIN2 / IIP2)
Earth loop tamper indication (ELT)
In case the power measurements from both current channels
differ by more than 12.5%, (indicating a earth loop tamper
condition), the ELT output is set to zero. The SA9607P
continues to generate output pulses from the larger of the two
measured powers in this condition. The ELT output is active
low.
Direction indication (DIRO)
The SA9607P provides information about the energy flow
direction on pin DIRO. A logic 1 on pin DIRO indicates reverse
energy flow. Reverse energy flow is defined as the condition
where the voltage sense input and a current sense input are
out of phase (greater than 90 degrees).
Positive energy flow, when voltage sense and current sense
input are in phase, is indicated on pin DIRO as a logic 0.
The DIRO pin may be used to drive a LED in order to indicate
reverse energy.
