ADuM1234 是一款隔离式半桥栅极
drive，采用ADI公司
iCoupler®技术，提供独立且隔离的高端和低端输出。这款隔离器件将高速CMOS与单芯片变压器技术融为一体，具有优于光耦合器解决方案的出色性能特征。
The iCoupler gate driver does not require LEDs and photodiodes, providing precision timing characteristics that optocouplers cannot provide. In addition, it does not have the reliability and performance stability issues associated with optocoupler LEDs.
Compared to gate drivers that employ a high-voltage level-shifting approach, the ADuM1234 offers true galvanic isolation between the inputs and outputs. Each output can operate up to ±700 VPEAK relative to the input, allowing low-end switching to negative voltage. The differential voltage between the high end and the low end can reach up to 700 VPEAK.
As a result, the ADuM1234 can reliably control the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
