Abstract
A system, method and circuit for providing constant current to an LED array are described herein. These include a resistor coupled to the LED array and a thermistor coupled to the LED array and the resistor. The resistor and the thermistor limit the current at a given temperature and compensate for the forward voltage shift of the LED array as a function of temperature. The system, method and integrated circuit may also include a fuse coupled to the thermistor. The fuse allows the system to continue to operate if a single LED within the LED array fails to short-circuit.
