Product Details

The ADuM4120/ADuM4120-1 are 2 A isolated, single-channel drivers that employ Analog Devices, Inc., iCoupler® technology to provide precision isolation. The ADuM4120/ADuM4120-1 provide 5 kV rms isolation in the 6-lead wide body SOIC package with increased creepage. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics, such as the combination of pulse transformers and gate drivers.

The ADuM4120/ADuM4120-1 operate with input supplies ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM4120/ ADuM4120-1 offer the benefit of true, galvanic isolation between the input and the output.

Options exist for models with and without an input glitch filter. The glitch filter helps reduce the chance of noise on the input pin triggering an output.

As a result, the ADuM4120/ADuM4120-1 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.

Applications

  • Switching power supplies 
  • IGBT/MOSFET gate drivers
  • Industrial inverters 
  • Gallium nitride (GaN)/silicon carbide (SiC) power devices
