Maxim Integrated Products introduces the 78M6631, a Teridian 3-phase power measurement system-on-chip (SoC) that embeds power monitoring into high-load applications. This self-contained and customizable energy measurement system offers a full range of measurement and diagnostics, resulting in ease of design and reduced costs. The 78M6631 is suited for a wide variety of applications requiring 3-phase power and quality measurements, including industrial panels and motors, solar panel inverters, storage power supplies, and data centers.

The self-contained energy measurement system features an embedded metrology engine and includes a full range of embedded energy diagnostics, including power factor, harmonic distortion, voltage sag, and dip. The 78M6631 also provides better than 0.5% system accuracy across a wide 2000:1 dynamic range. This enables the use of the lowest value shunt for the current sensor, thereby reducing heat and parasitic power loss. The device’s integrated flash provides application flexibility, on-chip calibration, and field upgrade capability. Furthermore, the 78M6631 is available with preloaded firmware that supports both Delta and Wye 3-phase applications, which reduces development costs and time to market.

The 78M6631 is available in a small, lead-free 56-pin QFN package, for designs where power density and space are at a premium. Demo kits are also available.
