Teridian 78M6618 Energy Measurement SoC

Teridian Semiconductor 78M6618

Teridian Semiconductor today announced the launch of its new energy measurement system-on-chip (SoC), the 78M6618 (6618), for use in data center power distribution units (PDUs) and applications in the smart home, including intelligent power strips and circuit breaker panels. The new chip is the industry’s first and only SoC that enables power metering, monitoring and intelligent relay control of eight single phase outlets simultaneously. In addition, the 6618’s unique ability to monitor and control eight channels at once can be extended to 32 or more channels by connecting multiple chips together.

The latest addition to Teridian’s new energy measurement product family, the 6618 adds a new level of ‘intelligence’ to PDUs that will enable the reduction of drastic failures and critical downtime by allowing administrators to better understand the power that is being used in the data center.

“When even one minute of downtime can equal millions of dollars in losses, quantifying and understanding minimum and maximum energy requirements of servers, power supplies, PDUs, and communication equipment on a per-outlet level is key,” said Jay Cormier, Teridian vice president and general manager, Energy Measurement & Communications. “We offer the additional advantage of an extremely clear value proposition over competing solutions as we can monitor eight outlets simultaneously with a single chip. Alternative solutions require eight chips and a microcontroller to achieve the same results.”
