... The device is able to switch all kind of resistive, inductive and capacitive loads, limited by current capabilities. The BTS3405G offers ESD protection of each IN Pin in relation to the corresponding Source Pin. The overtemperature protection is in order to prevent the device from overheating due to overload and/or bad cooling conditions. The temperature information is given by a temperature sensor in each of the two power MOSFET ...
