Below you can find information from the ADP3654 datasheet. Hope it helps.
INPUT DRIVE REQUIREMENTS (INA AND INB)
The ADP3654 is designed to meet the requirements of modern digital power controllers; the signals are compatible with 3.3 V logic levels…
Unfortunately, ADP3654 can't be used for half bridge topology to drive the top and the bottom MOSFETs. The isolated drivers are the ones we have for half bridge topology.
The ADP3654 is not meant for continuous operation at 2A current. It will not be able to sustain a DC current of 2A for long and will get hot. It will still be able to sustain it in my opinion but a more elegant solution is to simply use a V to…
