摘要： A guarded electronic circuit from reversal of its supply battery polarity comprises a MOS power transistor connected between one pole of the battery and ground, to drive an electric load to ground, and a second, protection MOS transistor connected between the pole and the first transistor; said transistors, which are both provided with respective inherent diodes between the source and the drain, have their related drain electrodes connected together. The resulting circuit is self-protected against possible reversal of the polarity of the battery to which it is connected, and can protect the electric load driven thereby.

摘要： A control circuit for switching inductive loads which can be monolithically integrated and used in high-speed printing equipment and in chopper power supply systems. The circuit includes a final power transistor, driven for switching by means of a drive transistor coupled to its control terminal. A speedup circuit is connected to the control terminals of both of the transistors in order to accelerate the turning off of the transistors by reducing the discharge time thereof. Such a speedup circuit is enabled so as to remove charge carriers only for a period of time which begins when the transistors are turned off in order to avoid additional time delays when the transistors are subsequently turned on again.

摘要： In this MOS-transistor bridge circuit, for obtaining a fast flyback conduction of the current after a normal operation of the circuit, instead of the flyback diodes associated with each transistor of the bridge, the MOS transistors themselves are employed, driven so as to conduct current from the ground to the power supply, that is in the opposite direction with respect to that of normal operation. For this purpose a control section is provided receiving at the input a fast flyback signal and comprising delay gates connected to the disable inputs of the transistors, so as to delay switching off thereof, and to maintain in the on state two diagonally opposed transistors so as to allow current to flow from the ground to the power supply through these diagonally opposed transistors and the load until the current decreases to zero.

The muting apparatus disables the output power amplifiers and controls signal levels at various positions in the power amplifier to reduce transient conditions. Control apparatus applies the muting signals to the power amplifier during a predetermined period during start-up of the amplifier and applies the muting conditions immediately upon the turning off of power to the power amplifier.

摘要： An output power stage which includes a PNP pull-up transistor and an n-channel FET push-down transistor, driven in phase opposition. This fully complementary stage provides an outstandingly improved power handling capability per semiconductor area occupied, together with a large output voltage swing, but does not require the use of externally connected discrete boot-strap components. The bipolar pull-up transistor can optionally be driven through an FET auxiliary stage, to minimize the power requirements of the preceding signal amplification stage.

摘要： A circuit for holding a MOS power transistor in a conduction state on the occurrence of an outage in the voltage supply, being of a type which comprises a first MOS transistor having its source connected to a line of the voltage supply and its drain connected to the gate of the power transistor, further comprises a diode connected between the drain of the first transistor and the gate of the power transistor, and a second transistor of the MOS type having its gate connected to the gate of the first transistor drain connected to the gate of the power transistor. The circuit prevents the gate capacitance of the power transistor from becoming discharged on a failure of the voltage supply, thus holding that transistor in a conducting state.

摘要： This circuit, for reliably driving a load both in DC and AC mode with a low dissipation, comprises a pair of MOS power transistors, in a push-pull configuration, and a bootstrap circuit including a bootstrap capacitor placed between the source of the upper MOS transistor and a reference voltage point, through a first switch. A second switch is arranged between the supply line and the gate of the upper MOS transistor, while a third switch is arranged between the gate of the upper MOS transistor and the point common to the first switch and the bootstrap capacitor. During DC operation, the switches are open or closed in order to allow for the connection of the gate of the MOS power transistor to the supply voltage. During AC operation, the switches are controlled thereby, alternately the capacitor is charged at the voltage of the reference voltage point and the upper MOS transistor is held at a gate-to-source voltage sufficient to feed the load.
