Detailed Description
The device is able to switch all kind of resistive, inductive and capacitive loads, limited by
current capabilities.
The BTS3205G offers ESD protection of the IN Pin in relation to the 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 the power MOSFET. During
thermal shutdown the device tries to sink an increased input current for feedback the fault condition.
The BTS3205G has a thermal-auto-restart function, the device will turn on again after the measured temperature
has dropped for the thermal hysteresis.
The over voltage protection is active during load-dump or inductive turn off conditions. The power MOSFET is
turned on if the Drain-source voltage gets too high. This function is available without supply.
