Abstract:
A switching device, comprising: a first and a second transistor connected in a half-bridge configuration, and each of the first and second transistors having a first and a second operating terminal and a control terminal for receiving a switching signal alternatively having a turn-on value and a turn-off value for taking each of the first and second transistors to an on state and to an off state, respectively;means for each transistor for detecting the state of the transistor and means for keeping the switching signal at the turn-off value when the state of the other transistor is the on state, the detecting means for detecting the state of the first and second transistors configured to output a state signal having a first and a second logic value corresponding to the on state and to the off state of the first and second transistors, respectively, and including a first and a second auxiliary transistor, respectively, each having a control terminal, a first operating terminal and a second operating terminal, the first and second transistor and each associated auxiliary transistor having the control terminal and the first operating terminal in common for receiving the switching signal.
