Detailed Description
The device is able to switch all kind of resistive, inductive and capacitive loads, limited by
current capabilities.
The BTS3104SDL 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 BTS3104SDL has a thermal-latch function. The device will turn off and stay off, even after the measured
temperature has dropped below the thermal hysteresis. After cooling down the device can be switched on again
by toggling the IN pin.
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
