8.3.3 Thermal Shutdown

If the junction temperature of the device exceeds the thermal shut down threshold of 170ºC the device turns off the CAN driver circuitry thus blocking the TXD to bus transmission path. The shutdown condition is cleared when the junction temperature of the device drops below the thermal shutdown temperature of the device. If the fault condition that caused the thermal shutdown is still present, the temperature may rise again and the device enters thermal shut down again. Prolonged operation with thermal shutdown conditions may affect device reliability. The thermal shutdown circuit includes hysteresis to avoid oscillation of the driver output.

NOTE

During thermal shutdown the CAN bus driver is turned off thus no transmission is possible from TXD to the bus. The CAN bus terminals are biased to recessive level during a thermal shutdown, and the receiver to RXD path remains operational.
