Abstract
The present invention relates to an apparatus and a method for protecting a MOSFET relay by using a voltage detector and a signal fuse, which calculate a detection voltage value through a voltage detector from an electrically conducted current value of a MOSFET relay provided in a battery main circuit for a vehicle and pre-block current applied to the MOSFET relay by operating a signal fuse when the calculated voltage value is more than a predetermined threshold to protect the MOSFET relay from being burned.
