Abstract
An apparatus for a circuit which allows a user to connect various adaptors to a common interface to provide a device with power and data signals. The circuit may provide a device, in which the circuit is incorporated, with the ability to discern whether a connected adaptor is providing power or data at any given time. If the adaptor is providing power at a particular moment, then the power/data circuit can identify that power is being provided and signal the device to accept power. When the adaptor is providing data at a particular moment, then the circuit can identify that power is being provided and signal the device to accept power. The circuit may include a power/data input, a vehicle connector, an internal power source connector, a reference voltage source, a comparator, and sensor.
