High Voltage, Isolated Gate Driver with  
Internal Miller Clamp, 2 A Output  
Data Sheet  
ADuM4121/ADuM4121-1  
FEATURES  
GENERAL DESCRIPTION  
2 A peak output current (<2 Ω RDSON  
2.5 V to 6.5 V input  
4.5 V to 35 V output  
Undervoltage lockout (UVLO) at 2.5 V VDD1  
Multiple UVLO options on VDD2  
Grade A: 4.4 V (typical) UVLO on VDD2  
Grade B: 7.3 V (typical) UVLO on VDD2  
Grade C: 11.3 V (typical) UVLO on VDD2  
Precise timing characteristics  
53 ns maximum isolator and driver propagation delay  
CMOS input logic levels  
High common-mode transient immunity: >150 kV/µs  
High junction temperature operation: 125°C  
Default low output  
)
The ADuM4121/ADuM4121-11 are 2 A isolated, single-channel  
drivers that employ Analog Devices, Inc.’s iCoupler® technology  
to provide precision isolation. The ADuM4121/ADuM4121-1  
provide 5 kV rms isolation in the wide-body, 8-lead SOIC package.  
Combining high speed CMOS and monolithic transformer  
technology, these isolation components provide outstanding  
performance characteristics superior to alternatives such as the  
combination of pulse transformers and gate drivers.  
The ADuM4121/ADuM4121-1 operate with an input supply  
ranging from 2.5 V to 6.5 V, providing compatibility with lower  
voltage systems. In comparison to gate drivers that employ high  
voltage level translation methodologies, the ADuM4121/  
ADuM4121-1 offer the benefit of true, galvanic isolation  
between the input and the output.  
Internal Miller clamp  
The ADuM4121/ADuM4121-1 include an internal Miller clamp  
that activates at 2 V on the falling edge of the gate drive output,  
supplying the driven gate with a lower impedance path to reduce  
the chance of Miller capacitance induced turn on.  
Safety and regulatory approvals (pending)  
UL recognition per UL 1577  
5 kV rms for 1-minute withstand  
CSA Component Acceptance Notice 5A  
VDE certificate of conformity (pending)  
DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12  
Options exists to allow the thermal shutdown to be enabled or  
disabled. As a result, the ADuM4121/ADuM4121-1 provide  
reliable control over the switching characteristics of insulated  
gate bipolar transistor (IGBT)/metal oxide semiconductor field,  
effect transistor (MOSFET) configurations over a wide range of  
switching voltages.
