The LT1796 CAN interface IC offers built-in fault tolerance to function in automotive and industrial environments. Discrete protection devices aren't required. Bus interface pins can withstand up voltage faults to ±60V with regard to earth with no damage to the unit. Faults may occur while the transceiver is active, closed down or powered off. On-chip ESD protection withstands around ±15kV air sparks and ±8kV contact style discharges analyzed per IEC-1000-4-2. Loss of ground or power connections doesn't harm the IC.
