Description

Description

The HLW8032 high-precision energy metering IC is a high-precision energy metering IC that uses a CMOS manufacturing process and is primarily intended for single-phase applications. It can measure line voltage and current and can calculate active power, apparent power, and power factor. The device integrates two ∑-Δ ADCs and a high-precision energy metering core. The HLW8032 can communicate data through the UART port. HLW8032 uses a 5V supply, a built-in 3.579M crystal oscillator, and an 8PIN SOP package. The HLW8032 has the advantages of high accuracy, low power consumption, high reliability, and strong adaptability to the environment. It is suitable for energy metering of single-phase two-wire power users.
