... The temperature information is given by a temperature sensor in the power MOSFET. During thermal shutdown the device sinks an increased input current at the IN pin to feedback the fault condition. The BTS3046SDR has a thermal-restart function. The device will turn on again, if input is still high, after the measured temperature has dropped below the thermal hysteresis. ...

... Overvoltage Protection When switching off inductive loads with low-side switches, the Drain-Source voltage potential, because the inductance intends to continue driving the current. Figure 13 Output Clamp The BTS3046SDR is equipped with a voltage clamp mechanism that prevents the Drain-Source voltage to rise V above . See Figure 13 ...

... The time from the beginning of current limitation until the over temperature switch off depends strongly on the cooling conditions. The device sinks higher current on IN pin during the protective switch off and switches back ON after the BTS3046SDR cools down below the temperature hysteresis . Figure 16 shows this behavior. ...
