GENERAL DESCRIPTION
TheADuM3224/ADuM42241 are 4 A isolated, half-bridge gate
drivers that employ the Analog Devices, Inc., iCoupler® technology
to provide independent and isolated high-side and low-side
outputs. The ADuM3224 provides 3000 V rms isolation in the
narrow-body, 16-lead SOIC package, and the ADuM4224 provides
5000 V rms isolation in the wide-body, 16-lead SOIC package.
Combining high speed CMOS and monolithic transformer
technology, these isolation components provide outstanding
performance characteristics superior to the alternatives, such as
the combination of pulse transformers and gate drivers.
The ADuM3224/ADuM4224 isolators each provide two
independent isolated channels. They operate with an input
supply ranging from 3.0 V to 5.5 V, providing compatibility
with lower voltage systems. In comparison to gate drivers
employing high voltage level translation methodologies, the
ADuM3224/ADuM4224 offer the benefit of true, galvanic
isolation between the input and each output. Each output can
be continuously operated up to 537 V peak relative to the input,
thereby supporting low-side switching to negative voltages. The
differential voltage between the high-side and low-side can be as
high as 800 V peak.
As a result, the ADuM3224/ADuM4224 provide reliable control
over the switching characteristics of IGBT/MOSFET configurations
over a wide range of positive or negative switching voltages.
