ADuM7223是一款
4 A isolated half-bridge gate driver，采用ADI公司
iCoupler®技术，提供独立且隔离的高端和低端输出。 这些隔离器件将高速CMOS与单芯片变压器技术融为一体，具有优于脉冲变压器和非隔离栅极驱动器组合等替代器件的出色性能特征。 通过在单封装内集成隔离器和驱动器，传播延迟最大值仅为60 ns，而通道间的传播偏斜最大值仅为7 ns。
The ADuM7223 provides two independent isolated channels. The ADuM7223 operates from a 3.0 V to 5.5 V supply voltage and is compatible with low-voltage systems. The output voltage is available in a wide range of 4.5 V to 18 V and is available in three output voltage versions. The 5 x 5 mm, LGA package offers 2500 V DC PEAK operating voltages (input-to-output and output-to-output).
These gate drivers have true galvanic isolation between the inputs and outputs compared to gate drivers that employ a high-voltage level-shifting approach. As a result, these gate drivers can reliably control the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.
