ADI ADUM7234BRZ

Магнитная муфта21000 Вrms

Overview

The ADuM7234 is an isolated, half-bridge gate driver thatemploys the Analog Devices, Inc., iCoupler® technology toprovide independent and isolated high-side and low-sideoutputs. Combining high speed CMOS and monolithictransformer technology, this isolation component providesoutstanding performance characteristics superior tooptocoupler-based solutions.By avoiding the use of LEDs and photodiodes, this iCouplergate drive device is able to provide precision timing characteristicsnot possible with optocouplers. Furthermore, the reliability andperformance stability problems associated with optocouplerLEDs are avoided.

As a result, the ADuM7234 provides reliable control over theswitching characteristics of IGBT/MOSFET configurations overa wide range of positive or negative switching voltages.
