the stmp01 is a single phase programmable energy metering ic with tamper detection from stmicroelectronics. it can measure active, reactive, apparent energies and rms values.
The STPM01 is a programmable single phase energy metering IC designed for effective measurement of active, reactive, and apparent energy in power line systems. It supports Rogowski coils, current transformers, and shunt sensors and can be implemented as a standalone meter or a peripheral in a microcontroller-based system.
The device includes an analog part with preamplifiers and A/D converters, and a digital part with a DSP unit and SPI interface. Key features include ripple-free active energy pulsed output, live and neutral monitoring for tamper detection, and easy digital calibration in a single point over the whole current range.
