    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,
