Fail-safe Functions
5.5 Overtemperature Protection
Figure 7 Overtemperature protection
The TLE7250GVIO has an integrated overtemperature detection circuit to protect the device against thermal
overstress of the transmitter. In case of an overtemperature condition, the temperature sensor will disable the
transmitter (see Figure 1). After the device cools down, the transmitter is activated again (see Figure 7).
A hysteresis is implemented within the temperature sensor.
