The IR2184 half bridge driver has a Vin spec of Vss +5 for absolute max and Vss + 4 for the recommended operation. This is confusing with a description of being "5V input logic compatible".
My design uses open drain logic with a 1K pull up to 5V. Input current is 25 to 60uA so the pull up could be increased to provide a voltage drop. A 20K would provide a 0.50 to 1.2V drop which would decrease the input voltage to (5- 0.50) 4.5V to (5-1.2) 3.8V. Is this the appropriate solution or am I misunderstanding the Vin spec? Thanks

Hi,
Thank you for posting at Infineon community.
I understood your concern and as per the values given ( minimum 3.8 V) , the IC input will work fine since the IC is compatible with 3.3 V and 5 V both as long as you keep the input current in limits.
I hope you understood.
