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.
