GENERAL DESCRIPTION
The ADuM4120/ADuM4120-1
1
are 2 A isolated, single-channel
drivers that employ Analog Devices, Inc., iCoupler® technology
to provide precision isolation. The ADuM4120/ADuM4120-1
provide 5 kV rms isolation in the 6-lead wide body SOIC package
with increased creepage. Combining high speed CMOS and
monolithic transformer technology, these isolation components
provide outstanding performance characteristics, such as the
combination of pulse transformers and gate drivers.
The ADuM4120/ADuM4120-1 operate with input supplies
ranging from 2.5 V to 6.5 V, providing compatibility with lower
voltage systems. In comparison to gate drivers employing
high voltage level translation methodologies, the ADuM4120/
ADuM4120-1 offer the benefit of true, galvanic isolation between
the input and the output.
Options exist for models with and without an input glitch filter.
The glitch filter helps reduce the chance of noise on the input pin
triggering an output.
As a result, the ADuM4120/ADuM4120-1 provide reliable
control over the switching characteristics of insulated gate
bipolar transistor (IGBT)/metal-oxide semiconductor field effect
transistor (MOSFET) configurations over a wide range of
switching voltages.
