Abstract
Systems and methods for advanced monitoring and control using an LED driver in an optical processor are described. In an embodiment, a monitoring and control circuit may include a light-emitting diode (LED) driver including a control input, an output, and a node, wherein the output is coupled to an LED. The circuit may also include a multiplexer coupled to the node of the LED driver, an analog-to-digital converter coupled to the multiplexer, and a controller coupled to the analog-to-digital converter and to the control input of the LED driver, wherein the LED driver is coupled to drive the output with a first voltage supply that is independent from a second voltage supply that is coupled to drive the controller.
