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
