GENERAL DESCRIPTION
The ADuM3220
based on the Analog Devices, Inc., iCoupler® technology.
Combining high speed CMOS and monolithic transformer
technology, this isolation component provides outstanding
performance characteristics superior to the alternatives, such
as the combination of pulse transformers and gate drivers.
The ADuM3220 isolator provides two independent isolation
channels. It has a maximum propagation delay of 60 ns and 5 ns
channel-to-channel matching. In comparison to gate drivers
employing high voltage level translation methodologies, the
ADuM3220 offers the benefit of true, galvanic isolation
between the input and each output, enabling voltage translation
across the isolation barrier. The ADuM3220 has shoot-through
protection logic and a default output low characteristic as
required for gate drive applications. It operates with an input
supply voltage ranging from 3.0 V to 5.5 V, providing compat-
ibility with lower voltage systems. The outputs may be operated
at supply voltages from 5 V to 18 V, which supports typical gate
drive voltages for synchronous dc/dc converters.
The ADuM3220 isolator contains various circuit and layout
enhancements to provide increased capability relative to
system-level IEC 61000-4-x testing (ESD, burst, and surge).
The precise capability in these tests is strongly determined by
the design and layout of the user’s board or module. For more
information, see the AN-793 Application Note, ESD/Latch-Up
Considerations with iCoupler Isolation Products.
The ADuM3220 specifies the junction temperature from −40°C
to 125°C.
