Claim 3:
4. The driving apparatus according to claim 2, wherein the first switch is turned ON when a voltage at a control terminal relative to a potential at an output terminal from which a current is output is greater than or equal to a second threshold value,
the driving apparatus further includes a second resistor that is connected between the control terminal and the output terminal of the first switch,
an input terminal of the first switch to which a current is input is connected to the gate of the MOSFET,
the output terminal of the first switch is connected to the source of the MOSFET,
the switching circuit includes:
a third switch that is turned ON when a voltage at a control terminal relative to a potential at an input terminal to which a current is input is less than a third threshold value; and
a third resistor that is connected between the control terminal and the input terminal of the third switch,

the input terminal of the third switch is connected to the direct current power source,
an output terminal of the third switch from which a current is output is connected to the control terminal of the first switch, and
the control terminal of the third switch is connected to an input terminal of the second switch to which a current is input.
