Abstract: A system for waking an electronic control unit upon movement of a controlled member, such as a vehicle lift gate or window, and protecting the electronic control unit from motor back EMF are provided. The system includes a power drive unit coupled to the controlled member and to the electronic control unit for moving the controlled member. A comparator subsystem is coupled to the power drive unit and is configured to compare an electrical output of the power drive unit generated due to motor back electromotive force in response to a manual movement of the controlled member to an electrical reference to determine whether to wake the electronic control unit. The system detects manual movement of the controlled member, e.g. from unauthorized entry, and causes an alarm and/or for the motor to brake or to drive to counteract the manual movement of the controlled member.
