ADUM4223

5 KV rms Isolated Precision Half-Bridge Driver, 4 A Output
Manufactured by:

Product Details

The ADuM3223/ADuM4223 are 4 A isolated, half-bridge gate drivers that employ the Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. The ADuM3223 provides 3000 V rms isolation in the narrow body, 16-lead SOIC package, while the ADuM4223 provides 5000 V rms isolation in the wide body, 16-lead SOIC package. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.

The ADuM3223/ADuM4223 isolators each provide two independent isolated channels. They operate with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM3223/ADuM4223 offer the benefit of true, galvanic isolation between the input and each output. Each output may be continuously operated up to 565 VPEAK relative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high-side and low-side may be as high as 800 VPEAK.

As a result, the ADuM3223/ADuM4223 provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.

Applications

  • Switching power supplies
  • Isolated IGBT/MOSFET gate drives
  • Industrial inverters

We were looking for a "isolated MOSFET switch" solution, tried the opto route (too slow), started to wind our own coils for inductive coupling (cumbersome) and finally found this chip and tested it. The results were/are excellent. We might still need to wind coils in the future and do this the hard way but only for HV cases ( 2kV). As long as we stay below this limit the AD chip is an excellent and cost-effective solution. Great job! If AD only offered this chip in an easier to manage casing (DIL)!

Dear sir; I use the ADUM4223 driver for full bridge. This is very good performance and easy to use with very few component. But protection issue with device how to solve like DESAT Detection, “Soft” IGBT Turn-off and Fault Feedback Under Voltage Lock Out (UVLO) Protection with Feedback Please suggest me Thanking You Ajeet K dhakar
