Detailed Description
The device is able to switch all kind of resistive, inductive and capacitive loads, limited by
current capabilities.
The BTS3046SDR offers ESD protection on the IN Pin which refers to the Source pin (Ground).
The overtemperature protection prevents the device from overheating due to overload and/or bad cooling
conditions. 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.
The over voltage protection gets activated during load dump or inductive turn off conditions. The power MOSFET
is limiting the drain-source voltage, if it rises above the
