Maxim – Self-contained power management SoC for three-phase POL applications (Maxim 78M6631)Feb 7 2012 - Power [More Power Articles]
Maxim Integrated Products (MXIM), has introduced the 78M6631, a Teridian 3-phase power measurement system-on-chip (SoC) that embeds power monitoring into high-load applications. The fully self-contained and customizable energy measurement system offers a full range of measurement and diagnostics, and results in ease of design and reduced costs. The 78M6631 suits 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.
“In end markets that require 3-phase energy monitoring, there is great demand for accurate energy measurement,” said Jay Cormier, Maxim Integrated Products director of energy measurement and communications. “Having the ability to monitor energy usage in applications that require 3-phase power can have a substantial impact on the energy consumption and efficiency in data centres, factories, and buildings. To reduce downtime, the 78M6631 enables measurement, diagnostics, and optimization of point-of-load problems before a potential equipment failure.”
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, thus reducing heat and parasitic power loss. The device’s integrated flash p= 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 both development costs and time to market.
“Leveraging more than 20 years of building metrology solutions, we can now address the specific measurement needs of 3-phase point-of-load applications,” added Cormier. “The simplified design and flexible capabilities of the 78M6631 will provide manufacturers with application-specific adaptability and an 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 density and space are at a premium. Production units of the 78M6631 are available now. Demo kits are also available, says the company.More news from Maxim
