FP131 OVER CURRENT PROTECTION IC General Description Download 　FP131 is a main rail current detection and over current protection IC. It is including a current shunt comparator, photo driver comparator with a non-inverting input precision reference regulator. The current shunt comparator has the any gain adjustable function for rail current detection using three external resistors, and the comparator non-inverting input has a 1.25V regulator for over current reference which is comparing with the output of shunt comparator and its output is driving the photo-coupler, and output active when the over current is occurred. FP131 is used with a few external parts for O.C.P. function and good active point during wide temperature range in secondary main rail power supply of SPS or DC-DC converter power supply application field. ˙Data Sheet   Features ˙Wide operating voltage range: +2.7V~ +28V ˙Independent shunt and supply voltage ˙Low input offset voltage ˙Sense gain adjustable ˙Comparator reference voltage: 1.25V (2%) ˙Output sink current capability up to 16mA ˙Package: PDIP8/SOP8
