BL0937 Single Phase Energy Meter IC

BL0937 Single Phase multi-function Energy Meter IC for smart Appliance

BL0937 IC is a single-phase multi-function energy meter IC for single-phase socket, Smart Appliance, with a low cost and high accuracy.

BL0937 energy meter IC integrates two high-accuracy Sigma-Delta ADC, voltage reference, power management and other analog circuit modules,and digital signal processing circuit to calculate active power, IRMS, VRMS etc. High frequency CF1 is provided for indicating IRMS/VRMS and high frequency CF for energy metering.

BL0937 can measure the single-phase active energy, active power, current and voltage RMS and other parameters to fully meet the needs of the socket, power strip, smart appliances and others
