HLW8032

HLW8032 is a high- precision electric energy metering IC which is manufactured using CMOS process and is mainly applied to single- phase application. It is able to measure line voltage and current and calculate active power, apparent power and power factor. The interior of the device integrates two Σ - Δ ADCs and one high- precision inner core of electric energy metering. Able to communicate data via UART port, HLw8032 adopts 5V power supply and built- in 3.579M crystal oscillator, and uses SOP packaging with 8Pin. Featured with high precision, low power consumption, high reliability, strong adaptability to environment, etc., HLw8032 is applicable to electric energy metering for power consumers with single- phase two- wire system.
