BL0942 calibration-free Metering IC Datasheet
■BL0942 is a built-in clock calibration-free energy metering IC, which is suitable for single-phase multi-function electricity meters, smart sockets, smart home appliances and other applications, with more cost-efficient solution.
■BL0942 incorporates two sigma delta ADC with a high accuracy energy measurement core. It measures line voltage and current and calculate active energy as well as instantaneous voltage and current.
■BL0942 provides access to on-chip registers via UART/SPI interfaces. One configurable low jitter pulse output Pin provide pulse that is proportional to active energy. Zero-crossing voltage (ZX_V), zero-crossing current (ZX_I) and overcurrent are accessible via the external pin.
■BL0942 has a patent active power no-load detection to prevent meter-creep.
