Isolated, Precision Half-Bridge  
Driver, 0.1 A Output  
Data Sheet  
ADuM1234  
FEATURES  
GENERAL DESCRIPTION  
Isolated high-side and low-side outputs  
High side or low side relative to input: 700 V peak  
High-side/low-side differential: 700 V peak  
0.1 A peak output current  
The ADuM12341 is an isolated, half-bridge gate driver that  
uses the Analog Devices, Inc., iCoupler® technology to provide  
independent and isolated high-side and low-side outputs.  
Combining high speed CMOS and monolithic transformer  
technology, this isolation component provides outstanding  
performance characteristics superior to optocoupler-based  
solutions.  
CMOS input threshold levels  
High frequency operation: 5 MHz maximum  
High common-mode transient immunity: >75 kV/µs  
High temperature operation: 105°C  
Wide body, RoHS-compliant, 16-lead SOIC  
Safety and regulatory approvals  
UL recognition  
2500 V rms for 1 minute per UL 1577  
VDE certificate of conformity  
By avoiding the use of LEDs and photodiodes, this iCoupler gate  
drive device is able to provide precision timing characteristics  
not possible with optocouplers. Furthermore, the reliability and  
performance stability problems associated with optocoupler LEDs  
are avoided.  
In comparison to gate drivers that use high voltage level translation  
methodologies, the ADuM1234 offers the benefit of true galvanic  
isolation between the input and each output. Each output can be  
operated up to 700 V peak relative to the input, thereby supporting  
low-side switching to negative voltages. The differential voltage  
between the high side and low side can be as high as 700 V peak.  
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12  
V
IORM = 560 V peak  
APPLICATIONS  
Isolated IGBT/MOSFET gate drives  
Plasma displays  
Industrial inverters  
Switching power supplies  
As a result, the ADuM1234 provides reliable control over the  
switching characteristics of IGBT/MOSFET configurations over  
a wide range of positive or negative switching voltages.
