摘要
A method of managing an output voltage of a LED driver to prevent damage to a LED load coupled thereto from a transient current is described. The method includes energizing a LED driver coupled to a microcontroller circuit. The microcontroller circuit samples a plurality of signals from the LED driver circuit. Moreover, the microcontroller circuit determines if an interruption event has occurred. The interruption event may include a main voltage supply interruption, intermittently removing and reconnecting a load, such as a loose LED load, and hot-swapping one LED load for another. The method further includes preventing a transient current from damaging the LED load if the interruption event has occurred. A system including circuits related to the method are also described.
