Hi Fabio,

Yes, please see the data sheet and leverage the built in fault protections: "±45-V LIN bus fault tolerant, 42-V load dump support, undervoltage protection on VSUP, TXD dominant state time-out, thermal shutdown, unpowered node or ground disconnection fail-safe at system level" etc. Please see sections 9.3.9 -14 for more information, thanks.

Best Regards,

Michael.

Hi Fabio,

Could you help clarify what is being observed? What kind of fault occurs when under what conditions?
