摘要： The additional voltage drop across a guard diode against supply polarity inversion in an integrated bridge circuit for driving an external load and employing two high-side NPN power switches driven by two PNP transistors, all monolithically integrated using a junction-type isolation technique, is substantially eliminated by connecting the emitters of the two PNP drive transistors directly to the positive rail, i.e. to the anode of the guard diode. Integrated PNP transistors are per se intrinsically protected against polarity inversion and when so connected permit to reduce the overall voltage drop across the driving bridge circuit. Using a Zener diode as the guard diode and a second Zener diode connected in opposition to the first Zener between the cathode thereof and the negative supply rail an additional spike protection of the circuit's components is implemented.

摘要： An electric power generator which includes a component, for example, a Zener diode, connected in series with the usual return diode which is connected in parallel to the excitation winding of the alternator. The Zener diode makes it possible to set the discharging voltage due to the energy stored in the magnetic field associated with the inductance of the excitation winding at a relatively high level during high-voltage transients caused by the accidental disconnection of the wire connecting the alternator to a load or a terminal of the motor vehicle battery while it is in the charging stage. The result is a more rapid dissipation of the energy stored in the excitation circuit, and therefore results in an output transient having a reduced energy content. Thus, it is possible to construct a voltage regulator and such other devices as may be powered by the alternator in the form of low-voltage integrated circuits.

摘要： For detecting the position of a magnetic element having a field component zeroing in at least one point in space, typically in a plane, a plurality of elementary Hall-effect sensors are integrated side by side and aligned in a direction perpendicular to the zeroing field component and to the current flowing through the elementary sensors. The elementary sensor generating a zero output voltage therefore indicates the zero position of the field component and consequently the position of the magnetic element with respect to the position sensor, so that The outputs of the elementary sensors provide a quantized numeric code indicating the position of the magnetic element.

摘要： A micromachined device made of semiconductor material is formed by: a semiconductor body; an intermediate layer set on top of the semiconductor body; and a substrate, set on top of the intermediate layer. A cavity extends in the intermediate layer and is delimited laterally by bottom fixed regions, at the top by the substrate, and at the bottom by the semiconductor body. The bottom fixed regions form fixed electrodes, which extend in the intermediate layer towards the inside of the cavity. An oscillating element is formed in the substrate above the cavity and is separated from top fixed regions through trenches, which extend throughout the thickness of the substrate. The oscillating element is formed by an oscillating platform set above the cavity, and by mobile electrodes, which extend towards the top fixed regions in a staggered way with respect to the fixed electrodes. The fixed electrodes and mobile electrodes are thus comb-fingered in plan view but formed on different levels.

摘要： A bi-dimensional position sensor that can be advantageously used in the turn system controlled from the steering wheel of a vehicle. The sensor includes a permanent magnet fixed to a control lever so as to move in a plane along first and second directions and to rotate about a third direction orthogonal to the preceding ones. The permanent magnet is movable with respect to an integrated device including a first group of sensor elements arranged spaced along the first direction, a second group of sensor elements arranged spaced along the second direction and a third group of sensor elements detecting the angular position of the permanent magnet. Electronics integrated with the sensor elements generate a code associated with each position which the permanent magnet may assume and generate a control signal corresponding to the desired function.

摘要： An electrostatic cleaning structure of a hard disk driver is formed by a plurality of concentric conductive regions to which biasing pulse trains are supplied. Each biased conductive region generates an electric field attracting any dielectric particle. The pulse trains supplied to immediately adjacent conductive regions are phase-shifted by a predetermined time and in a direction linked to a desired direction of removal for the electrostatic particles. Voltage pulses sent to each conductive region are delayed with respect to voltage pulses sent to an immediately preceding conductive region in the direction of desired removal, and are advanced with respect the voltage pulses sent to an immediately successive conductive region.
