HLW8112

HLW8110/HLW8112 is a high precision power metering IC. It can measure line voltage and current, and calculate active power. It can measure Line Frequency and Power Factor. HLW8110/HLW8112 has three detection channels, including current detection channels A and B, and voltage detection channels. A channel and B channel can be used for current detection at the same time. B - channel can be used for current detection or leakage detection. HLW8112 contains two configurable pulse output pins, which can be used to acquire over - current, over - voltage, zero - crossing voltage or current detection and leakage detection through INT1 and INT2 pins. HLW8110/HLW8112 power metering IC uses 3.3V or 5.0V power supply with Internal Frequency Oscillator.
