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.
