ABSTRACT:
An electrical resource device of the present invention includes a current restriction portion for restricting current flowing in a semiconductor element based on a predetermined overcurrent restriction threshold by controlling the semiconductor element when the current detected by a current detecting portion exceeds the predetermined overcurrent restriction threshold. The predetermined overcurrent restriction threshold is defined based on a relationship between time and a change of a destruction current amount by which wiring may be destroyed, and is determined to be under the destruction current. Therefore, it is possible to prevent the wiring from being destroyed.
