Single Phase Power/Energy Metering IC with
Tamper Detection
SA9607M
FEATURES
s Provides direct interface to mechanical counters
s Monitors Live and Neutral for tamper detection
s Performs bidirectional energy measurement
s Various setup modes selectable
s Meets the IEC 521/1036 Specification for Class 1 AC Watt
hour meters
DESCRIPTION
The SAMES SA9607M is a single-phase bidirectional energy
metering integrated circuit. It provides a mono-chip 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.
Direction detection of energy flow as well as other common
tamper conditions are flagged.
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.
The power consumption on both the live and neutral are
continuously measured and the larger of the two is selected
for energy metering.
The SA9607M drives the calibration LED and the electro-
mechanical counter directly.
The SA9607M 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 calibration. With a bias resistor of
24kΩ optimum conditions are set. It may be varied within
±10% for calibration purposes. Any changes to the bias
resistor will affect the output pulse rate quadratically (i.e.(R
= +5%,(f=10%).
Motor pulse rate select (MP1 and MP0)
The pulse rate of the motor driver ouput of the SA9607M is
selected by the inputs MP1 and MP0. Three pulse rate options
are available as shown in the following table:

Please note that the device will not perform metering functions
as described in this document while in test mode.
Rated condition select (RATED)
The rated condition select pin gives the option of having a
3:2:1 scaling ratio of the rated current easily available. This
feature is particularly useful in circumstances where a
manufacturer requires a meter for use in a system rated for
two different conditions, for example 230V/60A and 230V/
40A. With the rated condition select the SA9607M allows for
the development of different rated meters requiring minimal
changes. The following table below lists the options available
(assuming the rated condition to be 230V/60A).

OUTPUT SIGNALS
Motor output (MOP, MON)
The MON pulse will follow the MOP pulse within 142ms. This
prevents that the motor armature is in the wrong position after
a power failure. Both MOP and MON outputs are active high.

Selected input indication (SEL1)
The SA9607M continuously compares the power consumptions
on current channel 1 inputs and current channel 2 inputs. The
larger of the two measurements are used for metering. The
SEL1 output pin indicates which channel is currently being
used for the pulse output.
