BL0937 high accuracy electrical energy measurement IC Application Note
■The BL0937 is a high accuracy electrical energy measurement IC intended for single-phase application. It measures line voltage and current and calculates active energy and instantaneous rms voltage and current. The devices are suitable for multifunction smart electricity meters, power distribution units for corporate data centers, and in-home energy monitors for consumers.
●Features：
■High accuracy, less than ±0.5% error over a dynamic range of 2500: 1
■High stability of large signal, in the condition of signal 300mA, less than ± 0.2% error in the output frequency fluctuation (CF).
■High stability of small signal, in the condition of signal 50mA, less than ± 0.3% error in the output frequency fluctuation (CF).
■Current and voltage RMS, current measurement range (4mA ~ 30A) @ 1mohm
■On-Chip anti-creep protection
■On-Chip power supply detector
■On-Chip voltage reference of 1.218V (Typical)
■On-chip oscillator as clock source, 2MHz (Typical)
■Single 3.3V supply, low power consumption (6mW Typical)
