IGZ,
The BS2 cannot drive motor current, it must be followed by a motor driver. Sorry for the bad news. The BS2 outputs can only supply a few milliamps of current at a maximum of 5 volts. The motor will need much more than that even if it is a 5 volt motor. If you are only driving the motor in one direction, you may be able to get away with a power darlington transistor feeding the motor. Can you give us more specifics about the motor and your application? In the meantime, don't drive the motor with BS2 so you can save yourself the cost of replacing that item.
