Isolated Precision Half-Bridge Driver, 4.0 A Output. The ADuM7223 is a 4.0 A isolated, half-bridge gate driver that employs Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 64 ns, and the propagation skew from channel to channel is a maximum of only 12 ns at 12 V.
