Hello,
The schematic looks good! It is recommended to have a 4.7nF cap in parallel with a 220nF cap on VBB. In addition, VOUT should have one 220nF cap to filter voltage transients.
This is in reference to the ESD standards in ISO7637-2
Moreover, I see that the RPROT resistor for sense is 0ohm. This should stay 15k like the I/O protection resistors on other routes.
BR,
Alan
