  "textContent": "A semiconductor device having a power source terminal, a ground terminal, an input terminal, an output terminal and a status output terminal. The semiconductor device includes a power semiconductor switch connected between the power source terminal and the output terminal, a logic circuit connected to the power semiconductor switch, and a ground terminal opening detection circuit connected to the ground terminal and the status output terminal. The logic circuit is configured to generate, according to a signal inputted to the input terminal, an output logic signal for turning on or off the power semiconductor switch. The ground terminal opening detection circuit is configured to detect a state in which the ground terminal is opened, based on a rise in a potential of the ground terminal, and to output, via the status output terminal, a detection signal in response to the detection of the state.",
