BL6523GX is a wide range single-phase multi-function electronic energy metering chip. It integrates 3 analog circuits such as high precision sigma delta ADC, reference voltage, power management and other analog circuit modules, as well as digital signal processing circuits for processing active power, depending on power and current and voltage value. It is suitable for single-phase multifunctional or single-phase power line carrier energy meter applications.
Features
