BTS3405GXUMA1

The BTS3405G is a two channel low - side power switch in PG - DSO - 8 - 25 package providing embedded protective functions. The device consists of two separate monolithic IC. Each with one 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 BTS3405G offers ESD protection of each IN Pin in relation to the corresponding 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 each of the two power MOSFET. During thermal shutdown the device tries to sink an increased input current at the corresponding IN pin to feedback the fault condition on this channel. The BTS3405G has a thermal - auto - restart function, the regarding channel 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, means without voltage on the IN pins.
