IDT Announces the Industry’s Widest Range Poly-Phase Power Metering Products for Smart Grid Applications

28 APRIL 2011

Integrated Device Technology, Inc., the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, announced a new family of poly-phase power metering ICs that offer the widest dynamic range and lowest temperature coefficient in the industry. These new devices allow smart energy meter manufacturers to increase performance while consolidating functionality and lowering cost. The poly-phase power metering ICs expand on IDT’s award-winning 90E2x family of single-phase devices.
The 90E32 and 90E36 poly-phase metering ICs feature the industry’s widest dynamic range of 5000:1 (90E32) and 6000:1 (90E36), and the lowest temperature coefficient with proprietary temperature compensation technology, offering superior performance over a wide range of usage patterns and environmental conditions, increasing flexibility for meter manufacturers. The devices are fully compliant with international (IEC, ANSI) and Chinese (GB, DL) standards, and can be used for both three-phase four-wire (3P4W) and three-phase three-wire (3P3W) active and reactive energy meters.

“These newest power metering products enrich IDT’s award-winning portfolio and address the demands of our customers, who have quickly made our single-phase devices a success,” said Sean Fan, vice president and general manager of IDT. “Our engineering and applications expertise helps to enable the rapid and economical deployment of smart grid technology across the globe. The wide dynamic range and low temperature coefficient specifications are exactly what smart energy meter manufacturers need for their next generation products.”

“We are pleased to see IDT announcing another innovative power metering IC, in addition to the previously introduced single-phase devices,” said Mr. Li Xianhuai, Chief Technical Officer of Wasion Group Limited, a premier energy meter manufacturer in China. “IDT enables us to offer differentiated features and performance to our end customers. The unprecedented wide range and high accuracy is critical for poly-phase meter applications and the smart grid infrastructure.”

In addition, the IDT 90E36 features an on-chip Discrete Fourier Transform (DFT) analysis engine with Total Harmonic Distortion (THD) detection, raw analog to digital converter (ADC) data access via a direct memory access (DMA) port and other versatile parameter measurement functions. These features provide added flexibility during the development process and expand the device’s applications to Data Acquisition Terminal (DAT) units and other electrical parameter monitoring instruments.

Pricing and Availability
The IDT 90E32 and 90E36 are currently sampling to qualified customers and are available in a 48-pin TQFP package. The IDT 90E32 and 90E36 are priced at $2.85 and $4.50 each for volumes of 10,000 units, respectively. For more information, please visit www.idt.com/go/powermeter
