2.3 A peak output current (<2 R ) The ADuM4120/ADuM4120-1 are 2 A isolated, single-channel
DSON_x
2.5 V to 6.5 V V input
DD1 drivers that employ Analog Devices, Inc., iCoupler technology
4.5V to 35 V V output
DD2 to provide precision isolation. The ADuM4120/ADuM4120-1
UVLO at 2.3 V V
DD1 provide 5 kV rms isolation in the 6-lead wide body SOIC package
Multiple UVLO options on V
DD2 with increased creepage. Combining high speed CMOS and
Grade A4.4 V (typical) positive going threshold
monolithic transformer technology, these isolation components
Grade B7.3 V (typical) positive going threshold
provide outstanding performance characteristics, such as the
Grade C11.3 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/s
ADuM4120-1 offer the benefit of true, galvanic isolation between
High junction temperature operation: 125C
the input and the output.
Default low output
Options exist for models with and without an input glitch filter.
Safety and regulatory approvals (pending)
The glitch filter helps reduce the chance of noise on the input pin
UL recognition per UL 1577
triggering an output.
5 kV rms for 1 minute SOIC long package
CSA Component Acceptance Notice 5A
As a result, the ADuM4120/ADuM4120-1 provide reliable
VDE certificate of conformity (pending)
