Sames SA9607P
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. The power consumption on both the live and neutral are continuously measured and the larger of the two is selected for energy metering.FEATURES
s s s s s Provides direct interface to mechanical counters Calibration and setup stored on external EEPROM - no trimpots required Monitors both Live and Neutral for tamper detection Performs bidirectional energy measurement Flexible programmable features s s s s s Meets the IEC 521/1036 Specification for Class 1 AC Watt hour meters Total power consumption rating below 25mW Adaptable to different types of sensors Operates over a wide temperature range Precision voltage reference on chip.DESCRIPTION
The SAMES 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 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-inline plastic (DIP-20) and small outline (SOIC-20) package types.
