Abstract
The present invention relates to a battery reverse voltage prevention system, and more particularly, to a battery reverse voltage prevention system, which prevents current of a battery from flowing to a resistor by connecting an additional P-type channel MOSFET to a P-type channel MOSFET gate terminal in the related art in order to prevent opening/closing of a P-type channel MOSFET from being delayed due to a resistor installed to limit capacitance and dark current generated by the P-type channel MOSFET in a battery reverse voltage prevention system in the related art, which includes the P-type channel MOSFET, thereby reducing an opening/closing delay time of the P-type channel MOSFET in the related art.
