Paper Abstract

This paper proposed an algorithm to generate I-t curve of an IPS from its simplified model. The model used electrical and thermal characteristics of IPS like its on resistance (RON), thermal resistances (Rth) and capacitances (Cth) of its thermal circuit and its thermal tripping/shutdown temperature (TSHUTDOWN). I-t curves are extremely important for selection of an IPS for a particular load and wire in automotive industry. If only the IPS can sustain the load current and can protect the wire in case of a fault, it can be used for the application. This evaluation can be easily performed with the help of IPS I-t curve. The I-t curve generated using this algorithm was compared with that provided by the company (in application note) for some IPS. An application example using the I-t curve was also described. Finally the limitation of the model was mentioned and its effect was discussed with the help of the application example.
