GENERAL DESCRIPTION
The ADuM1234
employs the Analog Devices, Inc. iCoupler® technology to
provide independent and isolated high-side and low-side
outputs. Combining high speed CMOS and monolithic
transformer technology, this isolation component provides
outstanding performance characteristics superior to
optocoupler-based solutions.
By avoiding the use of LEDs and photodiodes, this iCoupler
gate drive device is able to provide precision timing characteristics
not possible with optocouplers. Furthermore, the reliability and
performance stability problems associated with optocoupler
LEDs are avoided.
In comparison to gate drivers employing high voltage level
translation methodologies, the ADuM1234 offers the benefit
of true, galvanic isolation between the input and each output.
Each output can be operated up to ±700 V
input, thereby supporting low-side switching to negative voltages.
The differential voltage between the high side and low side can be
as high as 700 V
As a result, the ADuM1234 provides reliable control over the
switching characteristics of IGBT/MOSFET configurations over
a wide range of positive or negative switching voltages.
