7.3.10.2 Thermal Shutdown (TSD)

If the junction temperature of the TCAN1162-Q1 exceeds the thermal shutdown threshold, TJ > TSDR, the device transitions into fail-safe mode and disables the transceiver transmitter and receiver blocking transmission to and from the CAN bus. The TSD fault condition is cleared when the device junction temperature falls below the thermal shutdown temperature threshold, TJ < TSDF. If the fault condition that caused the TSD fault is still present, the temperature may rise again and the device enters thermal shutdown again. Prolonged operation with a TSD fault conditions may affect device reliability.
