Overtemperature Protection

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.
