Hiliwei Tech HLW8012

HLW8012 is single phase multifunction metering chip. The high frequency pulse CF is provided for the energy measurement and the high frequency CF1 for indicating the effective value of the current or the effective value of the voltage. The chip uses SOP8 package.

• High frequency pulse CF, indicating active power, meet the accuracy of 50/60Hz IEC 687/1036 standards, in the range of 1000:1 to reach 0.2% accuracy.
• High frequency pulse CF1 can be configured to output current or voltage RMS, in the range of 500:1 to reach of 0.5% accuracy.
• Built- in power supply monitoring circuit, when the power supply voltage is low to 4V, the chip will be reset.
• Built- in 2.43V voltage reference source; 5V power supply, operating current is less than 3mA.

• The occasion of measuring the voltage, current and power, such as single- phase multi- function meter, smart socket, digital meter, smart street lamps, small appliances, etc.
