Abstract :
The SPICE fuse models that are based on theoretical fuse behavior and data derived from faulted fuse tests are presented. An overview of SPICE fault analysis and a brief history of the models´ development are included. The limitations of each model and possible methods of overcoming them are examined. The most favored model is discussed in more detail. Its major advantages are: the more accurate prediction of the fuse resistance as the fuse element is heated during the fault event; and the capability of the model to know when to blow, based on fuse rating and fault current profile
