ADuM1234
GENERAL DESCRIPTION
The ADuM1234 1 is an isolated, half-bridge gate driver that
uses the Analog Devices, Inc., i Coupler? 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 i Coupler 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 that use 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 peak 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 V peak.
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.
