GENERAL DESCRIPTION
The ADuM3220 / ADuM3221 1 are isolated, 4 A dual-channel gate
drivers based on the Analog Devices, Inc., i Coupler? technology.
Combining high speed CMOS and monolithic transformer technol-
ogy, these isolation components provide outstanding performance
characteristics superior to the alternatives, such as the combination
of pulse transformers and gate drivers.
The ADuM3220 / ADuM3221 provide digital isolation in two
independent isolation channels. They have a maximum propagation
delay of 60 ns and 5 ns channel-to-channel matching. In comparison
to gate drivers that employ high voltage level translation method-
ologies, the ADuM3220 / ADuM3221 offer the benefit of true,
galvanic isolation between the input and each output, enabling
voltage translation across the isolation barrier. The ADuM3220
has shoot-through protection logic, which prevents both outputs
from being on at the same time, whereas the ADuM3221 allows
both outputs to be on at the same time. Both parts offer a default
output low characteristic as required for gate drive applications.
The ADuM3220 / ADuM3221 operate with an input supply voltage
ranging from 3.0 V to 5.5 V, providing compatibility with lower
voltage systems. The outputs of the ADuM3220A / ADuM3221A
can be operated at supply voltages from 4.5 V to 18 V. The outputs
of the ADuM3220B / ADuM3221B can be operated at supply
voltages from 7.6 V to 18 V.
The junction temperature of the ADuM3220 / ADuM3221 is
specified from ?40°C to +125°C.
Qualified for automotive applications
