Energy-Measurement SoC Sets Up Shop In Data Center PDUs

The 78M6618, an energy measurement system-on-chip (SoC), finds employment in data center power distribution units (PDUs) and applications in the smart home including intelligent power strips and circuit breaker panels. The device is supposedly 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 chip’s ability to monitor and control eight channels at once can be extended to 32 or more channels by connecting multiple chips together. Other features include an accuracy of better than ±0.5% over a 2000:1 dynamic range with self calibration, a 32-bit compute engine, an MPU core, flash memory, a 22-bit delta-sigma ADC, 10 analog inputs, a precision voltage reference, and digital temperature compensation. Pricing for the 78M6618 is $5.90 each/1,000. TERIDIAN SEMICONDUCTOR CORP., Irvine, CA. (714) 508-8800.
