Classification: CPC H | IPC H

Claim 0:
1. A driving apparatus for driving a load, comprising:
an N-channel MOSFET that is disposed downstream of the load on a current path of a current that flows via the load;
a resistor that is connected between a direct current power source and the gate of the MOSFET;
a first switch that is connected between the gate and the source of the MOSFET;
a second switch that 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 threshold value;
a switching circuit connected to the direct current power source and interposed between the second switch and the first switch, the switching circuit configured to turn the first switch ON when the second switch is turned ON and turn the first switch OFF when the second switch is turned OFF by processing the direct current power source; and
an output unit configured to output a voltage relative to the potential at the output terminal of the second switch to the control terminal of the second switch.
