1. , a kind of semiconductor device, it carries out the semiconductor device of drive controlling to the 1st and the 2nd switching device between the main power source current potential of the main power source current potential that is connected in series, is inserted in high potential and electronegative potential, it is characterized in that:

  • Possess;

    High potential portion, it comprises the control part that the conduction/non-conduction of hot side switching device in the above-mentioned the 1st and the 2nd switching device is controlled;

    The low potential side logical circuit, it is arranged on main power source current potential with above-mentioned electronegative potential and is the benchmark electronegative potential portion that carries out work, generates the 1st state with the conducting of the above-mentioned hot side switching device of expression and the control signal of representing the 2nd state that above-mentioned hot side switching device is non-conduction according to the signal that applies from the outside, and produces the 1st and the 2nd pulse signal accordingly according to above-mentioned control signal and the above-mentioned the 1st and the 2nd state;

    The the 1st and the 2nd level shift portion, it carries out level shift with the above-mentioned the 1st and the 2nd pulse signal to above-mentioned high potential portion, obtains the pulse signal that the 1st and the 2nd level shift finishes respectively;

    AndVoltage detector component, it is arranged on above-mentioned electronegative potential portion, thus be used for detecting at least one side'"'"'s output line in the above-mentioned the 1st and the 2nd level shift portion current potential, give logical value according to this current potential to above-mentioned low potential side logical circuit the work of above-mentioned low potential side logical circuit controlled.
