ABSTRACT:
A temperature-sensitive semiconductor device, such as a laser diode, is protected against damage from overheating by use of a temperature sensor which produces a signal that is digitized and applied to a microprocessor. The microprocessor uses a look-up table to determine an appropriate duty cycle for operation of the semiconductor device, based upon the temperature of the semiconductor device, so as to avoid operating the semiconductor devices for a length of time which could produce overheating and damage.
