BL0942 Single Phase Energy Meter IC

BL0942 Calibration free Energy Meter IC

BL0942 is a built-in clock calibration-free energy measurement chip, suitable for single-phase multi-function energy meters, smart sockets, smart home appliances, etc. application, with high cost performance. BL0942 integrates 2 channels of high-precision Sigma-Delta ADC, reference voltage, power management and other analog circuit modules, as well as active power processing

BL0942 can measure current, voltage effective value, active power, active electric energy and other parameters, and can output fast current effective value (using for over-current protection), as well as waveform output and other functions, and output data through the UART/SPI interface, which can fully meet the needs of smart sockets and smart homes. It meets the needs of electricity, single-phase multi-function electric energy meters and big data collection of electricity consumption information. BL0942 has a patented anti-sneak design, combined with reasonable external hardware design, to ensure that the noise power is not included in the power supply when there is no current.

DNA solutions, Nashik has various types of Energy Meter IC. Check out our complete collection of Power  IC.

• Two independent Sigma-Delta ADCs, one for current and one for voltage.
• Current effective value range (10mA~30A) @1mohm
• Active power (1w~6600w)@1mohm@220V
• Can output current and voltage effective values, fast current effective values, active power, current and voltage waveform phase angle
• The factory gain error of the batch is less than 1%, and the peripheral components can be calibrated if they meet certain conditions.
• The current channel has overcurrent monitoring function, and the monitoring threshold and response time can be set
• Voltage/current/current zero-crossing signal output
• Built-in waveform register, which can output waveform data for load type analysis
• SPI (fastest speed supports 900KHz)/UART (4800-38400bps) communication method
• Power failure monitoring, when the voltage is lower than 2.7V, the chip enters reset state
• Built-in 1.218V reference voltage source
• Built-in oscillation circuit, clock is about 4MHz
• Single working power supply of the chip is 3.3V, low power consumption 10mW (typical value)
• SSOP10L/TSSOP14L package
