ADUM3221 Isolated 4 A Dual-Channel Gate Driver
The ADuM3220/ADuM3221
are isolated, 4 A dual-channel gate
drivers based on the Analog Devices, Inc., iCoupler® technology.
Combining high speed CMOS and monolithic transformer technology,
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 methodologies,
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.
