ADuM1230
GENERAL DESCRIPTION
The ADuM12301 is an isolated half-bridge gate driver that
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 VP relative to the 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 VP.
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.
