Abstract: A first terminal receives a first DC voltage. A switch selectively couples the first terminal to a second terminal providing an output. A control circuit selectively actuates the switch in response to a comparison of the first DC voltage to a second DC voltage. A low-dropout (LDO) linear voltage regulator, connected between the first and third terminals, operates to provide the second DC voltage from the first DC voltage.

Abstract: According to one aspect, an integrated circuit includes: an electronic module configured to generate a voltage at an output, and an electronic control circuit coupled to an output of the electronic module, the electronic control circuit comprising an emissive electronic component. The electronic control circuit is configured to cause the emissive electronic component to emit light radiation as a function of a value of the voltage at the output of the electronic module relative to a value of an operating voltage of the electronic module, and the operating voltage is specific thereto during normal operation of this electronic module. The light radiation emitted by the emissive electronic component is configured to diffuse to an outer face of the integrated circuit.

Abstract: The integrated circuit includes a first node intended to be biased at a first voltage, a second node intended to be biased at a second voltage and having a non-negligible capacitive coupling with the first node. A power supply management device comprises a voltage booster configured to boost a power supply voltage and comprising boost stages configured to generate intermediate voltages on intermediate nodes. A compatibility detection circuit is configured to detect compatibility between the second voltage and one of the intermediate voltages, and, if the second voltage is compatible with an intermediate voltage, to couple the at least one second node to the compatible intermediate node.

Abstract: An integrated circuit chip includes a front face having an electrical connection pad. An overmolded encapsulation block encapsulates the integrated circuit chip and includes a front layer at least partially covering a front face of the integrated circuit chip. A through-hole the encapsulation block is located above the electrical connection pad of the integrated circuit chip. A wall of the through-hole is covered with an inner metal layer that is joined to the front pad of the integrated circuit chip. A front metal layer covers a local zone of the front face of the front layer, with the front metal layer being joined to the inner metal layer to form an electrical connection. The inner metal layer and the front metal layer are attached or anchored to activated additive particles that are included in the material of the encapsulation block.

Abstract: An H-bridge circuit includes a supply voltage node, a first pair of transistors and a second pair of transistors. First transistors in each pair have the current paths therethrough included in current flow lines between the supply node and, respectively, a first output node and a second output node. Second transistors in each pair have the current paths therethrough coupled to a third output node and a fourth output node, respectively. The first and third output nodes are mutually isolated from each other and the second and fourth output nodes are mutually isolated from each other. The H-bridge circuit is operable in a selected one of a first, second and third mode.
