Isolated, 4 A Dual-Channel Gate Driver Data Sheet ADuM3220/ ADuM3221 FEATURES GENERAL DESCRIPTION 4 A peak output current
The ADuM3220/ADuM32211 are isolated, 4 A dual-channel gate
Precise timing characteristics
drivers based on the Analog Devices, Inc., iCoupler® technology.
60 ns maximum isolator and driver propagation delay
Combining high speed CMOS and monolithic transformer technol-
5 ns maximum channel-to-channel matching
ogy, these isolation components provide outstanding performance
High junction temperature operation: 125°C
characteristics superior to the alternatives, such as the combination
3.3 V to 5 V input logic
of pulse transformers and gate drivers.
4.5 V to 18 V output drive
The ADuM3220/ADuM3221 provide digital isolation in two
UVLO at 2.5 V VDD1
independent isolation channels. They have a maximum propagation
ADuM3220A/ ADuM3221A U VLO at 4.1 V VDD2
delay of 60 ns and 5 ns channel-to-channel matching. In comparison

to gate drivers that employ high voltage level translation method-
Thermal shutdown protection at >150°C
ologies, the ADuM3220/ADuM3221 offer the benefit of true,
Output shoot-through logic protection on the ADuM3220
galvanic isolation between the input and each output, enabling
Default low output
voltage translation across the isolation barrier. The ADuM3220
High frequency operation: dc to 1 MHz
has shoot-through protection logic, which prevents both outputs
CMOS input logic levels
from being on at the same time, whereas the ADuM3221 allows
High common-mode transient immunity: >25 kV/μs
both outputs to be on at the same time. Both parts offer a default
Enhanced system-level ESD performance per IEC 61000-4-x
output low characteristic as required for gate drive applications.
Safety and regulatory approvals UL recognition
The ADuM3220/ADuM3221 operate with an input supply voltage
2500 V rms for 1 minute per UL 1577
ranging from 3.0 V to 5.5 V, providing compatibility with lower
