DESCRIPTION

continuously measured and the larger of the two is selected for

energy metering.

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.

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.

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 SA2007P integrated circuit is available in 20 pin dual-in-

line plastic (DIP-20) and small outline (SOIC-20) package

types.

The power consumption on both the live and neutral are
