BL BL0972

BL0972 is a clock-built-in, calibration-free energy metering IC, suitable for applications requiring metering such as e-bike charging stations, PDUs, circuit breakers, and 4~20mA analog acquisition. It integrates two high-precision Sigma-Delta ADCs capable of simultaneously measuring 2 channels of signals (current or voltage). It can measure parameters including RMS current, RMS voltage, active power, and active energy, with support for fast RMS current output (for fault detection such as overvoltage and overcurrent), waveform output, and other functions. Data is output via a high-speed SPI interface.
