High Voltage, Isolated Gate Driver with Internal Mil er Clamp, 2 A Output Data Sheet ADuM4121/ ADuM4121-1 FEATURES GENERAL DESCRIPTION 2 A peak output current (<2 Ω RDSON)
The ADuM4121/ADuM4121-11 are 2 A isolated, single-channel
2.5 V to 6.5 V input
drivers that employ Analog Devices, Inc.’s iCoupler® technology
4.5 V to 35 V output
to provide precision isolation. The ADuM4121/ADuM4121-1
Undervoltage lockout (UVLO) at 2.5 V VDD1
provide 5 kV rms isolation in the wide-body, 8-lead SOIC package.
Multiple UVLO options on VDD2
Combining high speed CMOS and monolithic transformer
Grade A: 4.4 V (typical) UVLO on VDD2
technology, these isolation components provide outstanding
Grade B: 7.3 V (typical) UVLO on VDD2
performance characteristics superior to alternatives such as the
Grade C: 11.3 V (typical) UVLO on VDD2
combination of pulse transformers and gate drivers.
Precise timing characteristics
The ADuM4121/ADuM4121-1 operate with an input supply
53 ns maximum isolator and driver propagation delay
ranging from 2.5 V to 6.5 V, providing compatibility with lower
CMOS input logic levels
voltage systems. In comparison to gate drivers that employ high
High common-mode transient immunity: >150 kV/µs
voltage level translation methodologies, the ADuM4121/
High junction temperature operation: 125°C
ADuM4121-1 offer the benefit of true, galvanic isolation

Internal Miller clamp Safety and regulatory approvals ( pending)
The ADuM4121/ADuM4121-1 include an internal Mil er clamp

that activates at 2 V on the fal ing edge of the gate drive output,
5 kV rms for 1-minute withstand
