Energy Metering IC Vendors and Manufacturers

This page lists energy metering IC vendors and manufacturers, along with example part numbers.

About Energy Metering ICs:

Energy metering ICs are designed for a wide array of applications, including:

• Energy metering systems
• Solar inverters
• Power quality monitoring
• Process monitoring
• Protective devices

These ICs take analog inputs (typically AC/DC current and AC/DC voltage) and output various energy measurements (active, reactive, and apparent). They calculate these energy values and store them in internal registers accessible via a microcontroller using SPI or I2C interface lines.

Key Technical Specifications for Selection:

When choosing an energy metering IC, consider these specifications:

• Analog inputs
• Output interface (SPI or I2C)
• Active Energy, Reactive Energy, and Apparent Energy measurements
• Clock input and clock output
• Harmonic measurements
• RMS measurements
• Mean Absolute Value
• Interrupt request outputs
• Frequency output
