GENERAL DESCRIPTION
The ADuM1230
employs Analog Devices’ 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 ADuM1230 offers the benefit of
true, galvanic isolation between the input and each output. Each
output may be operated up to ±700 V
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 ADuM1230 provides reliable control over the
switching characteristics of IGBT/MOSFET configurations over
a wide range of positive or negative switching voltages.

... The transient of the linear component is given by dV /dt = ΔV/Δt CM The ADuM1230’s ability to operate correctly in the presence of linear transients is characterized by the data in Figure 8. The data is based on design simulation and is the maximum linear transient magnitude that the ADuM1230 can tolerate without an operational error. This data shows a higher level of robustness ...

... To accommodate these situations, users can choose either a gate driver with a stronger output stage or the buffer configuration with the ADuM1230, as shown in Figure 14. In many cases, the buffer configuration is the less expensive of the two options and provides the greatest amount of design flexibility. The precise buffer/high voltage transistor combination can be selected to fit the application’ ...
