GENERAL DESCRIPTION
The ADuM3223/ADuM42231 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 ADuM3223 provides 3000 V rms
isolation in the narrow body, 16-lead SOIC package, and the
ADuM4223 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.
49 ns maximum isolator and driver propagation delay
5 ns maximum channel-to-channel matching
CMOS input logic levels
The ADuM3223/ADuM4223 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
ADuM3223/ADuM4223 offer the benefit of true, galvanic
isolation between the input and each output. Each output may
be continuously operated up to 560 VPEAK relative to the input,
thereby supporting low-side switching to negative voltages. The
differential voltage between the high-side and low-side may be
High common-mode transient immunity: >50 kV/µs
Enhanced system-level ESD performance per IEC 61000-4-x
High junction temperature operation: 125°C
Default low output
Safety and regulatory approvals (pending)
ADuM3223 narrow body, 16-lead SOIC
UL 1577 3000 V rms input-to-output withstand voltage
ADuM4223 wide body, 16-lead SOIC
UL 1577 5000 V rms input-to-output withstand voltage
as high as 700 VPEAK.
As a result, the ADuM3223/ADuM4223 provide reliable
control over the switching characteristics of IGBT/MOSFET
configurations over a wide range of positive or negative
switching voltages.
