Maxim's Teridian™ Power Measurement and Monitoring SoC enabling an integrated energy measurement solution for 3-phase POL (point-of-load) applications

SUNNYVALE, CA—February 6, 2012—Maxim Integrated Products (NASDAQ: MXIM) has launched the Teridian™ 3-phase power measurement SoC 78M6631, which provides power monitoring capabilities for high-load applications. This customizable integrated measurement system offers the full range of measurements and diagnostics, simplifies design, and reduces costs. The 78M6631 is suitable for a wide range of applications requiring 3-phase power and quality measurements, including industrial panels and motors, solar panel inverters, storage power supplies, and data centers.

Jay Cormier, Head of Energy Measurement and Communications at Maxim Integrated Products, explained, "There is a high demand for precise energy measurement in end markets requiring three-phase energy monitoring. Equipping applications where three-phase power is essential with energy usage monitoring capabilities can have a significant impact on energy consumption and efficiency in data centers, factories, and buildings. The 78M6631 measures, diagnoses, and optimizes POL issues before device failure occurs to reduce downtime."

This self-operating energy measurement system features an integrated metering engine and provides a full range of built-in energy diagnostics, including power factor, harmonic distortion, transient voltage drops, and voltage dips. The 78M6631 offers system accuracy of over 0.5% over a wide dynamic range of 2000:1, enabling the use of low-resistance shunt sensors for current sensing, which reduces heat dissipation and parasitic power losses. The device's embedded flash memory provides application flexibility, automatic calibration, and field upgrade capabilities. Furthermore, the 78M6631 comes with built-in firmware that supports both Delta and Wye 3-phase applications, which can reduce both development costs and time to market.

"With building metering solutions backed by over 20 years of accumulated experience, we are now able to address the specific measurement needs of three-phase POL applications," said Cormier, adding, "The streamlined design and flexible capabilities of the 78M6631 provide manufacturers with application-specific adjustments and unprecedented time-to-market."

The 78M6631 power measurement and monitoring SoC is available in a small, lead-free 56-pin QFN package for designs where power consumption and space are critical considerations. The 78M6631 is currently in mass production, and demo kits are available.
