Fail Safe Functions

6.5

Overtemperature Protection

Integrated overtemperature detection protects the TLE9255W from thermal overstress of the transmitter. The

overtemperature protection is active in Normal-operating Mode only. The temperature sensor provides the

temperature threshold TJSD. If the junction temperature exceeds the upper threshold TJSD, then the TLE9255W

disables the transmitter and sets the bit TSD, indicating that a critical temperature situation is reached. After

the device cools down the transmitter is re-enabled. Only an SPI command can reset the TSD bit. A hysteresis

is implemented within the temperature sensor.

Delay Time for Mode Change

The TLE9255W performs mode changes within the time window tMode_Change. During mode changes

(tMode_Change) the RxD output pin is permanently set to “high” and does not reflect the status on the CANH and

CANL input pins. After the mode change is completed, the TLE9255W releases the RxD output pin.
