  • MOS power device usable both as an N-channel MOS transistor and as a P-channel MOS transistor
    Patent number: 4764692
    Abstract: An N-channel power switch is controllable through two inputs by typical control signals for N-channel and P-channel MOS transistors. In the first case the control signal is brought back with unchanged polarity on the gate of the power switch which consequently operates in the peculiar manner of an N-channel device. In the second case the control signal charges a capacitor which reproduces on the gate of the power switch the same operating condition, causing it to operate again as an N-channel device although with P-type control.
