Abstract
A semiconductor apparatus is provided, comprising a power semiconductor element which is connected between a first terminal on a high-potential side and a second terminal on a low-potential side and is controlled to be turned on or off according to a gate potential, a cut-off condition detection section which detects whether or not a control signal that is input from a control terminal and controls the power semiconductor element satisfies a predetermined cut-off condition, and a cut-off circuit which controls the gate potential of the power semiconductor element to be an OFF potential in response to the cut-off condition detection section detecting that the cut-off condition is satisfied, and the cut-off condition detection section has an input terminal connected to the first terminal and the control terminal, and uses an electrical signal input from the input terminal as a power source.
