Abstract
A driver device of a data interface includes an input/output (I/O) interface, a power interface, a transmitter circuit, and a switching unit. The I/O interface is configured to couple to a load device. The power interface is configured to provide a power supply for transmitting data via the I/O interface. The transmitter circuit is coupled to the I/O interface and to the power interface and is configured to be powered by the power supply and provide an output signal to the load device via the I/O interface in a transmitter mode. The switching unit is coupled to the power interface and is configured to switch off the power interface for the transmitter circuit when the transmitter circuit is operating in a low power state. The transmitter circuit has a power consumption level below a threshold power level in the low power state.
