Abstract
A semiconductor control device includes a switching element including a main element, and a sense element connected in parallel with the main element; and a control circuit configured to bias a sense electrode of the sense element by a negative voltage, and to detect a leakage current of another switching element connected in series with the main element. The control circuit biases the sense electrode by the negative voltage, for example, so as to turn on the sense element, without turning on the main element.
