ADUM7234BRZ

门驱动器 Prec Half-Bridge Dvr 4A Output

Isolated, Precision  Half-Bridge Driver, 4 A Output

GENERAL DESCRIPTION ADUM7234BRZ

The ADuM72341 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.
