Abstract
A power circuit switching device includes two switching terminals; a high voltage depletion mode transistor and a low voltage enhancement mode transistor arranged in series between the two switching terminals; a control circuit having a first input for receiving a switching signal and a second input for receiving a signal for activating the device, the control circuit being configured to put the switching device into an inactive state or an active state; a driver circuit for applying the switching signal to the gate of the high voltage transistor, the driver circuit being supplied with a first voltage from a first voltage source (VDR+) and with a second voltage from a second voltage source (VDR−), the first and second voltages being respectively higher and lower than the threshold voltage of the high voltage transistor; and at least one programming module associated with the driver circuit, configured to program the incoming current which is to be injected at the gate of the high voltage transistor, and the outgoing current which is to be drawn from the gate; the programming module being able to be connected to a first and a second passive component for programming the incoming current and outgoing current, respectively.
