4 A Dual-Channel Gate Driver  
ADuM3220  
FEATURES  
GENERAL DESCRIPTION  
4 A peak output current  
Precise timing characteristics  
60 ns maximum isolator and driver propagation delay  
5 ns maximum channel-to-channel matching  
High junction temperature operation: 125°C  
3.3 V to 5 V input logic  
The ADuM32201 is a 4 A isolated, dual-channel gate driver  
based on the Analog Devices, Inc., iCoupler® technology.  
Combining high speed CMOS and monolithic transformer  
technology, this isolation component provides outstanding  
performance characteristics superior to the alternatives, such  
as the combination of pulse transformers and gate drivers.  
4.5 V to 18 V output drive  
The ADuM3220 isolator provides two independent isolation  
channels. It has a maximum propagation delay of 60 ns and 5 ns  
channel-to-channel matching. In comparison to gate drivers  
employing high voltage level translation methodologies, the  
ADuM3220 offers 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 and a default output low characteristic as  
required for gate drive applications. It operates with an input  
supply voltage ranging from 3.0 V to 5.5 V, providing compat-  
ibility with lower voltage systems. The outputs may be operated  
at supply voltages from 5 V to 18 V, which supports typical gate  
drive voltages for synchronous dc/dc converters.  
UVLO at 2.5 V VDD1 and 4.1 V VDD2  
Thermal shutdown protection at >150°C  
Output shoot-through logic protection  
Default low output  
High frequency operation: dc to 1 MHz  
CMOS input logic levels  
High common-mode transient immunity: >25 kV/μs  
Enhanced system-level ESD performance per IEC 61000-4-x  
UL 1577 2500 V rms input-to-output withstand voltage  
(pending)  
Small footprint and low profile  
Narrow body, RoHS-compliant, 8-lead SOIC  
5 mm × 6 mm × 1.6 mm  
The ADuM3220 isolator contains various circuit and layout  
enhancements to provide increased capability relative to  
system-level IEC 61000-4-x testing (ESD, burst, and surge).  
The precise capability in these tests is strongly determined by  
the design and layout of the user’s board or module. For more  
information, see the AN-793 Application Note, ESD/Latch-Up  
Considerations with iCoupler Isolation Products.  
APPLICATIONS  
Isolated synchronous dc/dc converters  
MOSFET/IGBT gate drivers  
The ADuM3220 specifies the junction temperature from −40°C  
to 125°C.
