TJA1055
Enhanced fault-tolerant CAN transceiver

Automatic reset to differential mode if bus failure is removed

Full wake-up capability during failure modes
2.3 Protections

Bus pins short-circuit safe to battery and to ground

Thermally protected

Bus lines protected against transients in an automotive environment

An unpowered node does not disturb the bus lines

Microcontroller interface without reverse current paths, if unpowered
2.4 Support for low power modes


limits the allowable
combinations of power dissipation (P) and operating ambient temperature (T
