ADuM3123
GENERAL DESCRIPTION
The ADuM31231 is a 4.0 A isolated, single channel driver that
employs Analog Devices, Inc., iCoupler® technology to provide
precision isolation. The ADuM3123 provides 3000 V rms
isolation in the narrow-body, 8-lead SOIC package. Combining
high speed CMOS and monolithic transformer technology,
these isolation components provide outstanding performance
characteristics superior to alternatives such as the combination
of pulse transformers and gate drivers.
The ADuM3123 operates 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 ADuM3123 offers the
benefit of true, galvanic isolation between the input and the
output. The output can continuously operate up to 380 V rms
relative to the input.
As a result, the ADuM3123 provides reliable control over the
switching characteristics of IGBT/MOSFET configurations over
a wide range of positive and negative switching voltages.
