Dear Suppport team

Hello I have question of TPS3803-Q1.

When Vin gradually fall down In below connection with setting the VIT to 2V,

My understanding is that It is hold RESET=L to VIN=2V - 0.8V, and it is less than 0.8V, reset output is indefinite. Is it correct?

Is there the method to fix output low Vin? (Please see attached file)
