ADuM1234
GENERAL DESCRIPTION
The ADuM12341 is an isolated, half-bridge gate driver that
uses 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 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.

2 The minimum pulse width is the shortest pulse width at which the specified timing parameters are guaranteed.
3 The maximum switching frequency is the maximum signal frequency at which the specified timing parameters are guaranteed.
4 tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
5 Channel-to-channel matching, rising or falling edges, is the magnitude of the propagation delay difference between two channels of the same part when the inputs
are either both rising or falling edges. The supply voltages and the loads on each channel are equal.
6 Channel-to-channel matching, rising vs. falling edges, is the magnitude of the propagation delay difference between two channels of the same part when one input is
a rising edge and the other input is a falling edge. The supply voltages and loads on each channel are equal.
7 Part-to-part matching, rising or falling edges, is the magnitude of the propagation delay difference between the same channels of two different parts when the inputs
are either both rising or falling edges. The supply voltages, temperatures, and loads of each part are equal.
8 Part-to-part matching, rising vs. falling edges, is the magnitude of the propagation delay difference between the same channels of two different parts when one input
is a rising edge and the other input is a falling edge. The supply voltages, temperatures, and loads of each part are equal.
