0 A Output ADuM7223 GENERAL DESCRIPTION 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.
The ADuM7223 provides two independent isolation channels.
The ADuM7223 operates with an input supply ranging from 3.
0 V to 5.
5 V, providing compatibility with lower voltage systems.
The outputs operate in a wide range from 4.
5 V to 18 V with three output voltage versions available.
The 5 mm × 5 mm, LGA package provides 565 V operating voltage from input to output and 700 V from output to output.
In comparison to gate drivers employing high voltage level translation methodologies, this gate driver offers the benefit of true, galvanic isolation between the input and each output.
As a result, this gate driver provides reli...
