Abstract: A power switch circuit for driving an airbag squib module has a power transistor, a pre-charge capacitance for storing a charge, a charging circuit and a controllable energy-coupling element. The power transistor has a first electrode, a second electrode and a control electrode. A path between the first electrode and the second electrode is connected in series with the airbag squib module between a supply potential and a reference potential. The charging circuit charges the pre-charge capacitance and the charging circuit is therefore coupled with the pre-charged capacitance. The controllable energy coupling element is connected between a first electrode of the pre-charge capacitance and the control electrode of the power transistor. The power switch exhibits a high degree of stability, allows a fast switching of the power transistor and further has an advantageous transient response.

The circuit includes a pulse width modulator circuit configured so as to provide a pulse-width-modulated actuating signal for the switch element depending on a regulating signal dependent on the output voltage and a current measurement signal dependent on a current across the inductive storage element. The circuit further includes an arrangement that provides the current measurement signal, wherein the arrangement for providing the current measurement signal is a measuring and regulating arrangement, configured so as to simulate the current measurement signal from a signal dependent on the output voltage, a signal dependent on the difference between the input voltage and the output voltage, and at least a first sampled value of a signal proportional to the current across the inductive storage element during a period of the pulse-width-modulated actuating signal.

Abstract: The n-channel VDMOS transistor is formed in an n-type active region of an integrated circuit with junction isolation. To prevent over-voltages between source and gate which could damage or destroy the gate dielectric, a p-channel MOS transistor is formed in the same active region and has its gate electrode connected to the gate electrode of the VDMOS transistor, its source region in common with the source region of the VDMOS transistor, and its drain region connected to the p-type junction-isolation region. The p-channel MOS transistor has a threshold voltage below the breakdown voltage of the gate dielectric of the VDMOS transistor so that it acts as a voltage limiter.

Abstract: An AB class stage is described which comprises two complementary MOSFET final transistors connected in a push-pull manner between two supply terminals. In order to attain high linearity, low switching distortion, a high ratio between the maximum output current and the rest current, independence of the rest current from the temperature and manufacturing variables and a circuit simplicity, the circuits determining the rest current and those which provide current to the load are substantially independent of one another. More particularly, two transconductance amplifiers are provided which control the final transistors and are dimensioned so as to have zero output current in rest conditions, two voltage generators which determine the rest current and two resistors being connected between the gate electrodes of the final transistors and the supply terminals.

Abstract: A circuit for dividing a reference current is composed of a number n of transistors connected in cascade, in a Darlington configuration, between current generator and a fractionary current output node and by N+k (where k is an integer different from zero) directly biased diodes in series, connected between the generator and the fractionary current output node. The circuit does not employ current mirrors, so all transistors may have the minimum size, which also minimizes the effects of leakage currents. Additionally, compensation elements may be used for compensating the leakage currents from the base regions of the transistors. The circuit is useful as a capacitance multiplier, or as a slow ramp generator in a large number of design situations. Independence from intrinsic parameters of the transistors used and/or from temperature of operation may be provided by employing a specifically designed reference current generator. Several embodiments are described.
