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.

1 All voltages are relative to their respective ground.
2 Input-to-output voltage is defined as GNDA − GND1 or GNDB − GND1.
3 Output differential voltage is defined as GNDA − GNDB.
4 Refers to common-mode transients across any insulation barrier. Common-
mode transients exceeding the Absolute Maximum Ratings can cause latch-
up or permanent damage.
ADuM1230
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Ambient temperature = 25°C, unless otherwise noted.

Notes
Output returns to input state within 1 μs of VDDI power restoration.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
