STPM33TR ST Energy Metering IC | 32-VFQFN Exposed Pad | 0.5% Accuracy, SPI Interface

Product Overview

The STPM33TR from STMicroelectronics is a highly integrated, single-phase energy metering IC designed for accurate active, reactive, and apparent energy measurement. It features a 32-VFQFN exposed pad package for enhanced thermal performance. The device includes two independent sigma-delta ADCs, a digital integrator, and a dedicated DSP for energy calculation. It supports both Rogowski coil and current transformer sensors, making it versatile for various metering applications. The STPM33TR communicates via SPI interface and provides instantaneous power, RMS voltage/current, and energy data. It operates over a wide supply voltage range of 2.95V to 3.6V and consumes only 5mA typical current, ideal for smart meters and industrial monitoring.
