HLW8012 SMD IC Energy Metering Hiliwei Tech SOP8 HLW8012

Product Overview:

A surface-mount, high-precision single-phase energy metering integrated circuit designed for smart power management and household electrical appliance monitoring applications. Fabricated using an optimized complementary metal-oxide-semiconductor (CMOS) process, it integrates two high-performance analog-to-digital converters, power calculation logic engines, and dual-frequency pulse output networks on a single monolithic chip. It requires very few peripheral components to accurately calculate active power, current root-mean-square (RMS) values, and voltage RMS values over wide dynamic ranges.

Core Specifications:

Manufacturer: HILIWI TECHNOLOGY (Shenzhen Hiliwi Technology Co., Ltd. / 合力为科技)

Package Type: SOP-8 (Surface Mount)

Function: High-Precision Single-Phase Power and Energy Metering IC

Input Channels: 2 Analog Input Channels (1 Differential Current Input Channel V1P/V1N and 1 Single-Ended Voltage Input Channel V2P)

Control Interface: 3-Wire Pulse and Selection Interface consisting of Power Pulse Output (CF), Current/Voltage Pulse Output (CF1), and Output Selection Input (SEL)

Features

• Multi-Parameter Real-Time Measurements: Computes active power, current root-mean-square values, and voltage root-mean-square values simultaneously.

• High-Linearity Pulse Output: Features a high-frequency pulse output (CF) directly proportional to active power, achieving a tight measurement accuracy error of less than 0.5 percent over a wide 1000:1 dynamic range.

• Dual-Function Configurable Output Channel: The secondary pulse output (CF1) can be dynamically toggled via the SEL pin to stream either high-frequency current RMS data or voltage RMS data.

• Built-in Stable Clock Oscillator: Houses an internal high-stability RC clock source running at a nominal frequency of 3.579 MHz, removing the need for an external crystal.

• Integrated Precision Voltage Reference: Features an on-chip, low-drift bandgap voltage reference providing a highly accurate 2.43V baseline for internal converters.

• Low Operational Power Footprint: Tailored for energy efficiency, maintaining a low typical operating current consumption of only 2.5 mA.

• Smart Power-On Initialization: Includes an onboard power supply voltage monitor circuit that automatically performs a reliable system reset during initial power-up.

Applications

• Smart WiFi Outlets and Plugs: Functions as the embedded metering core inside internet-connected smart plugs to monitor appliance energy metrics.

• Intelligent Electrical Power Strips: Implements multi-socket power monitoring, load tracking, and consumption logging.

• Household Appliance Energy Diagnostics: Integrated into smart TVs, air conditioners, and refrigerators to log real-time power profiles and optimize standby consumption.

• Server Farm Power Distribution Units (PDUs): Tracks localized rack power metrics to monitor computational energy efficiency and load balancing.
