I am planning to use TPS3808G33 fixed version with a threshold of 3.07.
Nominal supply for this component is 3.3V but in my case I will supply it with 1.8V (which seems acceptable from datasheet >1.7V) but will sense a 3.3V line still. RST output will be pulled up to 1.8V.
However I am not sure if the component can still keep the factory programmed threshold (3.07V) if I supply it with a lower VDD (1.8V)
Thanks Onur.
