Thank you for the answer !
That is, unless TPS386000 (or UC1903) is used,
Is it OK that negative voltage detection can not be done by TI devices?
Also, is it possible under the condition of "(2)"?

Antonio,
The TPS3700 can be used as a negative voltage detector but I don't think the simulation model works for negative voltage detecting. The actual device should work though as your schematic looks correct when compared to the recommended application…
