The condition short circuit is an overload condition of the device. If the current reaches the limitation value of
the device limits the current and starts heating up. When the thermal shutdown temperature is reached, the device
turns off.
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 .
