Abstract: A method of manufacturing a magnetic-field sensor includes forming an insulating layer on a first surface of a substrate. First and second magnetoresistors are formed at different above the first surface of the substrate and are spaced apart from the first surface by different distances. The first and second magnetoresistors have respective main axes of magnetization transverse to one another, and respective secondary axes of magnetization transverse to one another. The method further includes forming a first magnetic-field generator configured to generate a first magnetic field having field lines along the main axis of magnetization of the first magnetoresistor, and forming a second magnetic-field generator configured to generate a second magnetic field having field lines along the main axis of magnetization of the second magnetoresistor.

Abstract: A circuit includes a first transistor and a second transistor having respective control terminals coupled to receive first and second bias voltages. A first electronic switch is coupled in series with, and between current paths of the first and second transistors to provide an output current line between a circuit output node and ground. A second electronic switch is selectively activated to a conductive state in order to provide a charge transfer current path between a bias node and a charge transfer node in the output current line. A third electronic switch is selectively activated to a conductive state in order to provide a charge transfer current path between the charge transfer node and the control terminal of the second transistor.

Abstract: An electronic device for detecting the presence of an occupant on board a vehicle includes an audio sensor to acquire sound-sensing signals on board the vehicle. A movement sensor acquires movement-sensing signals associated with movement of the vehicle and an environmental sensor acquires environmental-sensing signals on board the vehicle. A processing unit is coupled to the audio sensor, movement sensor, and environmental sensor processes the respective sound-sensing signals, movement-sensing signals, and environmental-sensing signals to monitor the presence on board the vehicle of the occupant and the absence of a responsible person to determine a situation of danger and to activate a corresponding alarm warning.

Abstract: An electronic device includes a rectifier bridge that includes an input configured to be coupled to power over Ethernet (PoE) power sourcing equipment (PSE), and an output. A transistor is configured to selectively couple the output with a load. The electronic device includes a maintain power signature (MPS) device, and a control circuit. The control circuit is to maintain the transistor on when a load current is above a threshold, source current from the rectifier bridge to the MPS device when the load current is below the threshold, and switch the transistor to a diode configuration when the load current is below the threshold.

Abstract: A manufacturing method of an electronic device includes: forming a drift layer of an N type; forming a trench in the drift layer; forming an edge-termination structure alongside the trench by implanting dopant species of a P type; and forming a depression region between the trench and the edge-termination structure by digging the drift layer. The steps of forming the depression region and the trench are carried out at the same time. The step of forming the depression region comprises patterning the drift layer to form a structural connection with the edge-termination structure having a first slope, and the step of forming the trench comprises etching the drift layer to define side walls of the trench, which have a second slope steeper than the first slope.
