NORWOOD, Mass. (Business Wire EON) March 19, 2008 --
Analog Devices, Inc., a global leader in high-performance semiconductors
for signal-processing applications, is introducing the industry’s
first isolated half-bridge gate drivers that incorporate isolated power
and isolated gate drivers in one package. Competitive products, such as
optocoupler isolated gate drivers, require separate power isolation.
Integration eliminates components, reduces system cost and size by as
much as 50 percent, and improves system reliability and quality by
simplifying designs. Furthermore, the new products will come
pre-approved with safety approvals normally required for discrete-based
isolated power supplies.
Analog Devices’ engineers integrated an
isolated power supply and isolated gate drivers in the same package by
using the company’s award-winning iCoupler®
technology. This provides isolated high-side and low-side outputs
together with ADI’s proprietary isoPower™
integrated, isolated power. isoPower leverages iCoupler
technology’s chip-scale micro-transformers
along with high-voltage CMOS to create an isolated dc-to-dc converter.
About the ADuM5230 and ADuM6132 Isolated Half-Bridge Gate Drivers
The ADuM5230 and ADuM6132 are designed for implementations that include
motor drives, plasma displays, and power inverters found in power
supplies and solar power converters. On both devices, the integrated,
isolated converter powers both the high-side output as well as any
external buffer circuitry, eliminating the cost, space, and design
complexity associated with external power supply configurations.
The ADuM5230 and ADuM6132 differ in power capability and
high-side/low-side isolation configuration. In the ADuM5230, which
supplies 150 mW of power, the high-side and low-side outputs are
isolated from each other as well as from the inputs. In the ADuM6132,
which supplies 250 mW of power, only the high-side output is isolated
from the input.
In contrast to gate drivers employing high-voltage level translation
methodologies, the ADuM5230 and ADuM6132 offer the benefit of true
galvanic isolation between the inputs and outputs. On both products, the
outputs may be operated up to ±700 V (peak)
relative to each other. On the ADuM5230, the isolated outputs may be
operated up to ±700 V (peak) relative to the
inputs, thereby supporting low-side switching to negative voltages.
Availability and Pricing
The ADuM5230 will sample and be available in full production quantities
in April 2008. Housed in a wide-body SOIC (small-outline integrated
circuit) 16-lead package, the ADuM5230 is priced at $2.25 per unit in
1,000-unit quantities. For more information, visit http://www.analog.com/pr/ADuM5230.
The ADuM6132 is sampling now, and will be available in full production
quantities in July 2008. Housed is a wide-body SOIC 16-lead package, the
ADuM6132 is priced at $2.12 per unit in 1,000-unit quantities. For more
information, visit http://www.analog.com/pr/ADuM6132.
