DESCRIPTION
The SAMES SA2007P is a single phase bi-directional energy
metering integrated circuit. It provides a cost effective solution
for energy meters with electro-mechanical displays, such as
stepper motors and impulse counters. A precision oscillator,
that replaces an external crystal is integrated on chip.
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
continuously measured and the larger of the two is selected for
energy metering.
The SA2007P drives the calibration LED, the indicator LEDs
and the electro-mechanical counter directly.
The SA2007P does not require any external trim-pots. All
required calibration and configuration data is read from a small
external EEPROM.
The SA2007P integrated circuit is available in 20 pin dual-in-
line plastic (DIP-20) and small outline (SOIC-20) package
types.
