Fourth Generation ICs Eliminate Costly
Current Transformers
IRVINE, Calif., February 2,
2010 – Teridian
Semiconductor today announced that it has begun sampling its fourth
generation residential smart metering integrated circuits (ICs). The
new product family includes the 71M6541x and 71M6xx1 and features
digitally isolated current sensors based on the company’s
proprietary MicroDAATM isolation technology. The new 71M6541x, as a
stand-alone meter system-on-chip (SoC) for single element meters,
offers significantly reduced power consumption and enhanced
accuracy. The 71M6xx1 isolated sensor IC eliminates current
transformer and associated copper wiring in 2-element residential
meters, with up to class 0.2 accuracy (ANSI 200A). The result is up
to 25 percent reduction in bill of materials (BOM) costs for
residential applications.
The announcement of Teridian’s new
product line comes at the onset of major green initiatives and plans
by the U.S., Chinese and European governments to accelerate
deployment of smart metering solutions. The new smart metering
product family addresses the needs of this dynamic market and was
developed in response to customer demand for advanced products at a
lower cost point.
Teridian’s large portfolio of residential,
commercial and industrial energy metering and measurement devices
provides a highly accurate, reliable and cost-effective alternative
to multi-chip implementations and features better than 0.1 percent
accuracy over 2000:1 dynamic range and a unique 32-bit programmable
metrology engine, which can be adapted to meet changing utility
requirements.
“ By incorporating our proprietary isolation
technology into our high performance metering solutions we have
successfully overcome traditional barriers associated with the use
of resistive shunts in multi-phase applications. Hence, we’re
enabling our customers to reduce their product’s form factor, copper
content and magnetic tamper susceptibility, while preserving, and in
some cases improving, accuracy,” said Kourosh Boutorabi, vice
president and general manager, Teridian Semiconductor Advanced
Metering Infrastructure. “This solution is groundbreaking in the
sense that until now, a technically and commercially viable
alternative to current transformers has never been available to
metering OEMs.”
Teridian’s metering devices are in use today by more than
50 metering manufacturers and on more than 100 metering platforms.
To date, Teridian has shipped in excess of 40 million units and has
the largest market share of SoC metering devices. In April of last
year, Teridian’s 71M653x family of metering products was named
innovative technology of the year in the semiconductor category from
the Orange County, Calif. region of TechAmerica. To learn more about
