Energy-measurement SoC for AC/DC power supplies
A Maxim Integrated Products product story
Edited by the Electronicstalk editorial team Mar 14, 2011
The 78M6613 Teridian/Maxim energy-measurement system on chip (SoC) for AC/DC power supplies is said to bring a higher level of management and control to servers and other equipment in data centres.
The 78M6613 enables the capture and reporting of real-time energy data, which provides data-centre managers with the ability to quantify where energy is needed, being used and being stranded.
Maxim Integrated Products has announced the launch of a Teridian/Maxim energy-measurement system on chip, the 78M6613
Visibility into this critical data is a requirement in order to manage and control energy usage in power-starved data centres that cannot keep up with the growing demands placed upon them.
With an embedded analogue front-end and compute engine, small footprint and embedded firmware, the 78M6613 is specifically optimised to address the challenges of precision energy measurement inside AC/DC power supplies.
As with all Teridian/Maxim brand energy-measurement SoCs, the 78M6613 features accuracy of +/-0.5 per cent over a 2,000:1 dynamic range, but also provides powerful tools for self-calibration to help facilitate rapid design time and optimal manufacturing costs.
The 78M6613 is a highly integrated, single-phase, fully self-contained AC power-measurement and monitoring SoC integrated circuit with embedded AC load monitoring and control firmware.
The small 32-pin QFN package is suited for real-estate-limited designs such as power supplies, where power density and space are a premium.
The 78M6613 features the full range of AC power diagnostics, including power, power factor, voltage current, voltage sag and dip.
On-chip flash and a microcontroller (MCU) enable the storage of calibration coefficients and eliminate the need for external components.
Initially targeted at server power supplies, the 78M6613 is also suited to energy-measurement needs in data communications and storage equipment.
The flexibility of the platform also makes real-time energy measurement a reality for home appliances, home automation networks and building automation.
The 78M6613 is available in a 32-pin QFN package.
