  • The STPM3x is an ASSP family designed for high accuracy measurement of power and energies in power line systems using the Rogowski coil, current transformer or shunt current sensors. The STPM3x provides instantaneous voltage and current waveforms and calculates RMS values of voltage and currents, active, reactive and apparent power and energies. The STPM3x is a mixed signal IC family consisting of an analog and a digital section. The analog section consists of up to two programmable gain low-noise low-offset amplifiers and up to four 2nd order 24-bit sigma-delta ADCs, two bandgap voltage references with independent temperature compensation, a low drop voltage regulator and DC buffers. The digital section consists of digital filtering stage, a hardwired DSP, DFE to the input and a serial communication interface (UART or SPI). The STPM3x is fully configurable and allows a fast digital system calibration in a single point over the entire current dynamic range.

    主要特性

    • UART and SPI serial interface with programmable CRC polynomial verification
    • Programmable LED and interrupt outputs
    • Four independent 24-bit 2nd order sigma-delta ADCs
    • Two programmable gain chopper stabilized low-noise and low-offset amplifiers
    • Bandwidth 3.6 kHz at -3 dB
    • Vcc supply range 3.3 V ± 10%
    • Supply current Icc 4.3 mA (STPM32)
    • Input clock frequency 16 MHz, Xtal or external source
