9.3.10 Thermal Shutdown

The LIN transmitter is protected through a current limit, however, if the junction temperature of the device exceeds the thermal shutdown threshold, the device turns off the LIN transmitter circuit. Once the overtemperature fault condition has been removed and the junction temperature has cooled beyond the hysteresis temperature, the transmitter is re-enabled, assuming the device remained in the normal mode. During this fault, the transceiver remains in normal mode (assuming no change of state request on EN), the transmitter is disabled, the RXD pin reflects the LIN bus, INH remains on, and the LIN bus pullup termination remains on.
