ADuM1233

GENERAL DESCRIPTION

The ADuM12331 is an isolated, half-bridge gate driver that
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 ADuM1233 offers the benefit of
true, galvanic isolation between the input and each output. Each
output can 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

PEAK

.

As a result, the ADuM1233 provides reliable control over the
switching characteristics of IGBT/MOSFET configurations over
a wide range of positive or negative switching voltages.

APPLICATION NOTES

COMMON-MODE TRANSIENT IMMUNITY

In general, common-mode transients consist of linear and
sinusoidal components. The linear component of a common­mode transient is given by

V

where ΔV/Δt is the slope of the transient shown in
and

Figure 12.

The transient of the linear component is given by

dV

The ability of the ADuM1233 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 ADuM1233 can
tolerate without an operational error. This data shows a higher
level of robustness than what is listed in
transient immunity values obtained in
data and apply allowances for measurement error and margin.

TRANSIENT IMMUNITY (kV/µs)

The sinusoidal component (at a given frequency) is given by
