Abstract
A wake-up circuit is provided for a vehicle control module interconnected via a bus network to a vehicle data communication system of a motor vehicle. The wake-up circuit includes an input voltage source; a bus detection stage for detecting bus activity on the bus network, an input stage for supplying the input voltage, and an output stage for supplying an output voltage to the vehicle control module. In operation, the bus detection stage provides an input signal in response to detecting bus activity on the bus network. In response to receiving the input signal from the bus detection stage, the input stage supplies a voltage from the input stage to the output stage. The output stage in turn regulates the output voltage to the vehicle control module.
