Jiaming,

the TPS65381 has an included voltage monitoring. Why is additional circuit like TL7700 needed?

The IGN pin can be driven direct from the supply to turn the device on

The TPS65381 can cover all requested functionality because it's designed for safety applications.

If you need any additional information, please let me know.

Thanks and regards

Michael
