Teridian Introduces Three-Phase Metering System-On-Chip

Teridian Semiconductor announced the introduction of the 71M6523 Three-Phase Residential Metering System-On-Chip. According to the company, throughout the world, three-phase residential metering is becoming increasingly common, particularly to address higher residential energy demand in developing economies.

The single-chip 71M6523 is claimed to deliver unprecedented anti-tamper neutral current measurement accuracy of 0.4%, allowing the detection of smaller amounts of energy theft, and surpassing alternative solutions by a factor of two. Teridian’s Single Converter Technology™ and innovative system-on-chip approach is also claimed to eliminate the need to isolate individual phases using multiple regulators and isolation devices, speeding development time, improving meter reliability and performance and reducing overall system cost by as much as 40%.

"Until the introduction of Teridian’s 71M6523, meter manufacturers were forced into complex, less robust, less reliable meter designs cobbled together from many discrete components," said Steve McClure, Vice President of Marketing for Teridian. "Teridian’s renowned flexibility and worldwide metering application experience enables our customers to more quickly customize their products to meet varying utility requirements throughout the globe without costly hardware redesign."

According to the company, with this solution, energy measurement accuracy is enhanced, MTBF is increased, and EMI susceptibility and power consumption are reduced. The 71M6523 also offers advanced power management and tamper detection features. Battery back-up mode functionality includes allowing measurements to be displayed and updated, push-button wake-up from sleep mode, and communications and I/O.

The 71M6523 is currently available in production volumes, and pricing in 100K quantities is available upon request.
