Classification: CPC H | IPC H

Claim 11:
12. A device including a path for passing electric current from a power source, the device comprising:
a terminal connected to the power source in the path for passing electric current; and
a resettable electronic fuse configured as a single component in the path for passing electric current and electrically connected to the terminal, the resettable electronic fuse including, within a housing:
a semiconductor switch connected to the terminal and including a conductive state and a nonconductive state,
a driver circuit configured to control the semiconductor switch into either the conductive state or the nonconductive state,
a sensing circuit configured to sense the electric current from the power source, and
a comparing circuit configured to compare the electric current to a first reference value,
wherein the driver circuit is configured to control the semiconductor switch into the nonconductive state when the electric current is greater than or equal to the first reference value.
