    Abstract: An insulating encapsulation encapsulates a semiconductor die having an integrated Hall current sensor configured to measure an electric current flowing adjacent an active surface of the semiconductor die. An electrically conductive trace is embedded in the insulating encapsulation. First electrically conductive formations extend through the insulating encapsulation towards opposed ends of the electrically conductive trace. The first electrically conductive formations are configured to cause an electrical current subject to measurement to flow in a current flow path through the electrically conductive trace. Second electrically conductive formations extend through the insulating encapsulation towards the active surface of the semiconductor die. The second electrically conductive formations are configured to activate the Hall current sensor integrated in the semiconductor die.

    Abstract: Methods of operating an induction geyser include drawing current through a resonant tank via a transistor, generating a changing magnetic field around the resonant tank. Owing to the strategic placement of the resonant tank in proximity to a fluid tank, the changing magnetic field envelopes the fluid tank. In a first method, the voltage across the transistor's conduction terminals is monitored, and when this voltage surpasses a predefined threshold, indicating an overvoltage condition, a corrective action is initiated in which a gate driver pulls up a gate drive signal that drives the transistor. In a second method, the current flowing between the transistor's conduction terminals is monitored, and upon detecting an overcurrent condition where the current exceeds a set threshold the gate driver is activated to pull down the gate drive signal. Both methods aim to keep operation of the geyser within desired parameters.

    Abstract: The present description concerns a method of checking a first data element, executed by an electronic device comprising a processor and a memory, wherein said first data element is not stored in said memory and is divided in N second data elements independent from the first data element, each second data element being stored in said memory, and a result of an application of a XOR function to the N second elements being equal to the first data element, wherein an image of the first data element by a CRC function linear with respect to the XOR function is stored in said memory, and said method comprising a step, executed by said processor, of checking if said image of the first data element by said CRC function is equal to an application of the XOR function to the images of N second elements by said CRC function.

    Abstract: A semiconductor substrate has a substrate trench extending from a front surface and including a lower part and an upper part. A first insulation layer lines the substrate trench, and a first conductive material is insulated from the semiconductor substrate by the first insulating layer to form a transistor field plate electrode. A gate trench in the first insulation layer defines an integral part of the first insulating layer surrounding the first conductive material in an upper part of the substrate trench. A second insulating layer lines the semiconductor substrate at the upper part of the substrate trench in the gate trench. A second conductive material fills the gate. The second conductive material forms a transistor gate electrode that is insulated from the semiconductor substrate by the second insulating layer and further insulated from the first conductive material by the integral part of the first insulating layer.
