Integrated Device Technology, Inc. (IDT®)
(NASDAQ: IDTI), the Analog and Digital Company™ delivering essential
mixed-signal semiconductor solutions, today announced the industry's
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
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.
