Q: TPS3808 undefined output state by 1682396
I have a question about TPS3808's undifined output state.
Datasheet says when Vd is under 0.8V, reset signal is undefined.
Can i understand that reset signal can be both state high and low irrespective of Vsense signal?
If so, we cannot predict the state of reset pin in a short period when IC is powerd up.

You are correct that the TPS3808 "undefined" state means that we are not able to define if it is high or low. When the input voltage is less than 0.8V, the IC is not "awake" and not able to properly drive the output voltage. This is typically not a problem because there is not enough voltage for the processor to work with this low of an input voltage. Once the input voltage goes above 0.8V, the TPS3808 /RESET pin will have the proper state.
