ADUM3223ARZ

门驱动器 3kV RMS Prec Half- Bridge Dvr 4A Out

Isolated Precision Half-Bridge Driver,  4 A Output

GENERAL DESCRIPTION  ADUM3223ARZ

The ADuM3223/ADuM42231 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, and 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.
