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 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.
