SRC0CS25D !!!! In the material of the SRC0CS25D, there is threshold voltage and what is for in this component?

I did not understand that VCC range of the SRC0CS25D is 1V6-5V5 and the electrical specifications state Vth=(min,type,max)=(3v29,3v40,3v50). There is some uncertinity about the thereshold. If my VIN voltage (given to VCC pin of SRC0CS25D) is under 3.40v, the chip does not operate properly? There is someone who helps me?

I have the same question here, both values contradict each other in the datasheet.

Did you get a reply from ST?
