IDT Announces Industry's First Poly-phase Metering IC with Piecewise Non-linear Compensation Technology for Enhanced Accuracy

SAN JOSE, Calif. --(Business Wire)--

Integrated Device Technology (News - Alert), Inc. (IDT®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced the industry's first poly-phase metering IC with piecewise non-linear compensation technology for enhanced accuracy. The new device enriches IDT's award-winning power metering portfolio and is positioned to gain additional market share with Chinese and European electric utilities in smart grid applications.

The IDT 90E32AS is an enhanced poly-phase metering IC built upon the platform of IDT's previously announced 90E32 series. In addition to featuring the industry's widest dynamic range (5000:1) and lowest temperature coefficient (6 ppm/°C), the new device includes piecewise non-linear compensation technology, which enables customers to obtain near-perfect metering accuracy with low-cost external sensing components. The new metering IC also includes additional anti-tampering features that allow the device to detect abnormal currents in the absence of the three voltage phases. In this condition, the chip will enter a partial-measurement mode to measure the voltage, current, and mean power if the detected current exceeds a configured threshold. This gives the utility company a more accurate reading under atypical circumstances, and has become a requirement in some regions.

"IDT continues to release industry-first products to meet the demands of the rapidly growing China smart grid," said Sean Fan, vice president and general manager at IDT. "Our latest power metering IC builds upon the foundation of our high-volume portfolio and adds enhancements to meet the evolving requirements of major Chinese utilities, as well as markets beyond China. Going forward, we will continue to identify the critical needs of our customers and be the first to deliver the performance and features they need to build successful products."

The IDT 90E32AS can be used for both three-phase four-wire (3P4W) and three-phase three-wire (3P3W) active and reactive energy meters. Moreover, the expanded event detection functions allow designers to further monitor the power quality and improve their overall metering accuracy, while lowered power consumption (almost 50 percent savings) optimizes system overhead and facilitates the design of more compact smart metering modules.

Pricing and Availability


The IDT 90E32AS is currently sampling to qualified customers and is available in a 48-pin TQFP package. The IDT 90E32AS is priced at $2.85 for volumes of 10,000 units. For more information, please visit www.idt.com/go/PowerMeter.
