The LIN transmitter is protected by current-limiting circuit; however, if the junction temperature of the device exceeds the thermal shutdown threshold, the device puts the LIN transmitter into the recessive state and turns off the V_CC regulator. The nRST pin is pulled to ground during a TSD event. Once the over-temperature fault condition has been removed and the virtual junction temperature has cooled beyond the hysteresis temperature, the transmitter is re-enabled. During this fault the device enters a TSD off mode. Once the junction temperature cools, the device enters standby mode as per the state diagram.
