SA9607M

Single Phase Power/Energy Metering IC with Tamper Detection SA9607M FEATURES s s s s s Provides direct interface to mechanical counters Monitors Live and Neutral for tamper detection Performs bidirectional energy measurement Various setup modes selectable Meets the IEC 521/1036 Specification for Class 1 AC Watt hour meters s s s s 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 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. 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 electromechanical counter directly. The SA9607M integrated circuit is available in 20 pin dual-inline plastic (DIP-20) and small outline (SOIC-20) package types.
