STMicroelectronics Energy Meter IC 32-Pin QFN32L, STPM33TR [STPM33TR]; 151-469

The STMicroelectronics ASSP designed for high accuracy measurement of power and energies in power line systems using the Rogowski coil, current transformer or shunt current sensors. It provides instantaneous voltage and current waveforms and calculates RMS values of voltage and currents, active, reactive and apparent power and energies.

Dual mode apparent energy calculation

Instantaneous and averaged power

Under and overvoltage detection and monitoring

Overcurrent detection and monitoring

UART and SPI serial interface with programmable CRC polynomial verification

Programmable LED and interrupt outputs
