At least some embodiments include a LED driver system. The system includes multiple branches of series-coupled LEDs, multiple current sources, and control logic. Each of the current sources is coupled to a separate branch of series-coupled LEDs. The control logic is coupled to the current sources, and is configured to regulate current through each branch based at least in part on a feedback voltage measured at a node in one of the branches.

Systems and methods for driving light-emitting diodes

A serial data link () includes a transmitter () using a differential transmitter cell () to transmit data using differential signals and a receiver () using a differential receiver cell () to receive differential signals. When the transmitter () is in a power-down state, the differential signals from the differential transmitter cell () are set to an illegal state that is detected by the receiver cell (). Upon detecting the illegal state, unnecessary circuitry in the receiver () is shut off or placed in a low power state to conserve energy. When data transmission resumes, the receiver cell () automatically restores power to its circuitry and resumes receiving data.
