Circuit Protection
A current limiting circuit protects the CAN transceiver output stages from damage by
short-circuit to positive and negative battery voltages.
The CANH and CANL pins are protected against electrical transients which may occur
in the severe conditions of automotive environments.
The transmitter output stage generates the majority of the power dissipation. Therefore
it is disabled if the junction temperature exceeds the maximum value. This effectively
reduces power dissipation, and hence will lead to a lower chip temperature, while other
parts of the IC can remain operating.

Note: Maximum ratings are absolute ratings; exceeding one of these values may cause
irreversible damage to the integrated circuit.
