摘要： An integrated magnetic sensor formed in a body including a substrate of semiconductor material, which integrates a Hall cell. A trench is formed in the body, for example, on the back of the substrate, and is delimited by lateral surface portions that extend in a direction transverse to the main face of the body. The trench has a depth in a direction perpendicular to the main face that is much greater than its width in a direction parallel to the main face of the body, between the lateral surface portions. A concentrator made of ferromagnetic material is formed within the trench and is constituted by two ferromagnetic regions, which are set at a distance apart from one another and extend along the lateral surface portions of the trench towards the first Hall cell.

摘要： The integrated magnetic sensor for detecting an external magnetic field, is formed by a body of semiconductor material having a surface; an insulating layer covering the body of semiconductor material; a magnetically sensitive region, for example a Hall cell, extending inside the body; and a concentrator of ferromagnetic material, extending on the Hall cell and having a planar portion extending parallel to the surface of the substrate on the insulating layer. The concentrator terminates with a tip protruding peripherally from, and transversely to, the planar portion toward the Hall cell. When the magnetically sensitive region is a sensing coil of a fluxgate sensor, it is formed on the substrate, embedded in the insulating layer, and the tip of the concentrator can reach as far as the sensing coil.

摘要： A low-drop voltage regulator includes a P-type power transistor having an input terminal connected to a supply source, an output terminal connected to a load, and a control terminal driven by the output of an operational amplifier having its non-inverting input connected to a reference voltage source and its inverting input connected to the output terminal of the power transistor. To improve the regulation characteristics of the regulator without jeopardizing stability, even under normally critical conditions, provision is made for a feedback network including a capacitive component between the output and inverting input of the operational amplifier.

摘要： An H-bridge circuit which includes four power transistors (an npn pull-down and a pnp pull-up for each of the output terminals). Two control circuits are connected to drive these transistors in a complementary crossover configuration, so that each control circuit can turn on the pull-up transistor on one side of the load and the pull-down transistor on the opposite side of the load. Each of the power transistors is paralleled (base-to-base) by a smaller transistor which provides a scaled current output (proportional to that of the corresponding power transistor) to the opposite control circuit. The control circuit includes static current-thresholding disable logic, which prevents turn-on until the currents through the opposite power devices have declined to threshold levels. Thus, as long as either control circuit is driving one of the pull-up transistors into in the on-state, the other control circuit will not be able to turn on the pull-down transistor which is in series with the active pull-up transistor. This efficiently prevents any condition of unlimited crowbar current, without adding any excess delay or causing any high-impedance condition at the output.

摘要： An integrated magnetoresistive device, where a substrate of semiconductor material is covered, on a first surface, by an insulating layer. A magnetoresistor of ferromagnetic material extends in the insulating layer and defines a sensitivity plane of the sensor. A concentrator of ferromagnetic material including at least one arm, extending in a transversal direction to the sensitivity plane and vertically offset to the magnetoresistor. In this way, magnetic flux lines directed perpendicularly to the sensitivity plane are concentrated and deflected so as to generate magnetic-field components directed in a parallel direction to the sensitivity plane.
