Over-Temperature protection

The TLE8250G has an integrated over-temperature detection to protect the device against thermal overstress of

the output driver stage. In case of an over-temperature event, the temperature sensor will disable the output driver

stage (see Figure 1). After the device cools down the output driver stage is activated again (see Figure 7).

Inside the temperature sensor a hysteresis is implemented.
