Pin Selectable Three Phase Power / Energy Metering
IC for Stepper Motor / Impulse Counter Applications
with Anti Tamper Features
SA2005M
1/12
SPEC-0115 (REV. 3)
09-05-02

DESCRIPTION
The SAMES SA2005M provides a single chip active energy
metering solution for three phase mechanical counter-based
meter designs. Very few external components are required
and it has direct drive capability for electro-mechanical
counters.
The SAMES SA2005M is a CMOS mixed signal integrated
circuit that performs three phase power/energy calculations
over a range of 1000:1, to an overall accuracy of better than
Class 1.
The integrated circuit includes all the required functions for 3-
phase power and energy measurement such as oversampling
A/D converters for the voltage and current sense inputs, power
calculation and energy integration. Internal offsets are
eliminated through the use of cancellation procedures.
The SA2005M drives a calibration LED directly. Per phase
voltage fail and voltage sequence faults as well as energy
direction indication are available as LED outputs. Selectable
divider ratios enable various mechanical counter or stepper
motor counter resolutions.
A precision oscillator, that replaces an external crystal, is
integrated on chip. A voltage reference is integrated on chip.
The SA2005M integrated circuit is available in 24-pin dual in
line plastic (DIP-24) and small outline (SOIC-24) package
options.
