Isolated, Precision Gate Drivers with 2 A Output Data Sheet ADuM4120/ ADuM4120-1 FEATURES GENERAL DESCRIPTION 2.3 A peak output current (<2 Ω RDSON_x)
The ADuM4120/ADuM4120-11 are 2 A isolated, single-channel
2.5 V to 6.5 V VDD1 input
drivers that employ Analog Devices, Inc., iCoupler® technology
4.5V to 35 V VDD2 output
to provide precision isolation. The ADuM4120/ADuM4120-1
UVLO at 2.3 V VDD1
provide 5 kV rms isolation in the 6-lead wide body SOIC package
Multiple UVLO options on VDD2
with increased creepage. Combining high speed CMOS and
Grade A—4.4 V (typical) positive going threshold
monolithic transformer technology, these isolation components
Grade B—7.3 V (typical) positive going threshold
provide outstanding performance characteristics, such as the
Grade C—11.3 V (typical) positive going threshold
combination of pulse transformers and gate drivers.
Precise timing characteristics
The ADuM4120/ADuM4120-1 operate with input supplies
79 ns maximum isolator and driver propagation delay
ranging from 2.5 V to 6.5 V, providing compatibility with lower
falling edge (ADuM4120)
voltage systems. In comparison to gate drivers employing
CMOS input logic levels
high voltage level translation methodologies, the ADuM4120/
High common-mode transient immunity: 150 kV/μs
ADuM4120-1 offer the benefit of true, galvanic isolation between
High junction temperature operation: 125°C
the input and the output.
Default low output Safety and regulatory approvals (pending)
Options exist for models with and without an input glitch filter.
UL recognition per UL 1577
The glitch filter helps reduce the chance of noise on the input pin
