I require help on the TPS3808 part.
I need to know if the Pin VSENSE can have a higher voltage than VDD?
VSENSE is rated at 7V max as with VDD. But if VDD is 3.3V can VSENSE be 5V?

Yes, VSENSE is not referenced to VDD in the ABS MAX, so it is independent of the VDD voltage; and as discussed in this Design Note: http://e2e.ti.com/support/power_management/svs_and_sequencers/w/design_notes/tps3808gxx-can-sense-pin-voltage-exceed-supply-voltage.aspx
However, if VDD is not at the MIN voltage, the RESET output is undetermined.
