LIN-Slave for relay and DC motor control
4.2 Single DC motor drive with soft start / stop
For some applications it might be necessary:
• To control the motor speed especially during start / stop,
• To have an independent switching channel in case the relay “hangs”,
• To switch the power via the power transistor and to increase with this the life time of the relay
contacts
• To monitor the motor current (current sensing and over current shut off).
This application requires then also a reverse polarity protection in the power path.
Following application diagram shows the practical realization in principle:

switches and LIN bus, with soft start / stop and motor current sense
