STPMS1 Overview
The STPMS1, also called a smart-sensor device, is an ASSP designed for effective measurement in power line systems utilizing the Rogowski coil, current transformer, or shunt principle. It is used in bination with the STPMC1 programmable poly-phase energy calculator IC, as a building block for single-phase or poly-phase energy meters. The STPMS1 is a mixed signal IC consisting of an analog and a digital section.
