Abstract

Exemplary embodiments are disclosed of current control circuits and methods of modulating supply current from a first device (e.g., a telematics control unit (TCU), etc.) to one or more second devices (e.g., one or more compensators, etc.). In an exemplary embodiment, a method includes modulating a supply current from a first device to a second device into different current values for reporting different information from the second device to the first device. An exemplary embodiment of a current control circuit includes a variable voltage source electrically coupled with a current source and a current sink. The current control circuit is configured to modulate the supply current from a first device to the second device into different current values for reporting different information from the second device to the first device.
