BTS3205N

The BTS3205N is a one channel low-side power switch in PG-SOT-223-4 package providing embedded protective functions. The device is monolithic integrated and consist of an N-channel power MOSFET transistor and additional protection circuitry. The device is able to switch all kind of resistive, inductive and capacitive loads, limited by EAS and maximum current capabilities. The BTS3205N offers ESD protection of the IN Pin in relation to the Source Pin. 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 tries to sink an increased input current to feedback the fault condition. The BTS3205N has a thermal-auto-restart function, the device will turn on again after the measured temperature has dropped down for the thermal hysteresis. The over voltage protection is active during load-dump or inductive turn off conditions. The power MOSFET is limiting the Drain - Source voltage to the defined clamping voltage. This function is available regardless of the input pin state.
