ABSTRACT:
To a plurality of terminals are connected, one to one, a plurality of current mirror circuits each having a first load portion through which a first current flows when an overvoltage is applied and a second load portion through which a second current proportional to the first current flows. The first load portion of the current mirror circuit connected to one of the plurality of terminals is shared as the first load portions of the current mirror circuits connected to the others of the plurality of terminals. The shared first load portion includes an overvoltage protection circuit. The second load portions of the current mirror circuits connected to the plurality of terminals each include an overvoltage detection circuit for detecting the second current.
