Abstract: A protection circuit for an automotive wiring harness includes an input node receiving a sensing signal indicating intensity of current in a conductor, an output node emitting a current control output signal to reduce the current and/or emitting a warning signal indicating the current intensity having reached a limit value. Signal processing circuitry coupled to the input node compares the current intensity with a reference value, and produces a comparison signal indicating whether the current intensity exceeds the reference value. A counting circuitry driven by the comparison signal counts in a first count direction as a result of the comparison signal indicating that the current intensity exceeds the reference value. Latching circuitry coupled to the counter circuitry generates the output signal at the output node as a result of the count value of the counter circuitry reaching a limit value.

Abstract: A circuit for generating a bandgap voltage includes a circuit module for generation of a base-emitter voltage difference formed by a pair of PNP bipolar substrate transistors which identify a first current path and a second current path. A first current mirror of an n type is connected between the first and second branches and is further connected via a resistance for adjustment of the bandgap voltage to the second bipolar transistor. A second current mirror of a p type is connected between the first and second branches, and connected so that the current mirrors repeat current of each other. In operation to generate the bandgap voltage, current flows from the supply voltage to ground only through said the first and second bipolar substrate transistors.

Abstract: According to principles as discussed herein, an EEPROM cell is provided and then, after testing the code, using the exact same architecture, transistors, memory cells, and layout, the EEPROM cell is converted to a read-only memory (“ROM”) cell. This conversion is done on the very same integrated circuit die using the same layout, design, and timing with only a single change in an upper level mask in the memory array. In one embodiment, the mask change is the via mask connecting metal 1 to poly. This allows the flexibility to store the programming code as non-volatile memory code, and then after it has been tested, at time selected by the customer, some or all of that code from a code that can be written to a read-only code that is stored in a ROM cell that is composed the same transistors and having the same layout.

Abstract: A charge amplifier circuit is provided. The charge amplifier circuit is couplable to a transducer that generates an electrical charge that varies with an external stimulus. The charge amplifier circuit includes an amplification stage having an input node, couplable to the transducer, and an output node. The amplification stage biases the input node at a first direct current (DC) voltage. The charge amplifier circuit includes a feedback circuit, which includes a feedback capacitor, electrically coupled between the input and output nodes of the amplification stage. The feedback circuit includes a resistor electrically coupled to the input node, and a level-shifter circuit, electrically coupled between the resistor and the output node. The level-shifter circuit biases the output node at a second DC voltage and as a function of a difference between the second DC voltage and a reference voltage.

Abstract: A circuit for an ultrasonic channel has a first and a second terminal between which extend a resistive and diode signal paths including a pair of diodes with opposing polarities, for example in anti-parallel. Switching circuitry is coupled with the resistive and diode signal paths and is switchable between first and second states. In the first state, the first and the second terminals are coupled with one another via the resistive signal path. In the second state, the first and the second terminals are coupled with one another via the diode signal path. The switching circuitry includes first and second transistor discharge circuits coupled between first and second drive lines and current paths of these transistors, and coupled to control terminals of these transistors. The control terminals are coupled to the first or second drive line and are non-conductive and conductive in first and second operating states, respectively.

Abstract: A semiconductor die includes a structural body that has a power region and a peripheral region surrounding the power region. At least one power device is positioned in the power region. Trench-insulation means extend in the structural body starting from the front side towards the back side along a first direction, adapted to hinder conduction of heat from the power region towards the peripheral region along a second direction orthogonal to the first direction. The trench-insulation means have an extension, in the second direction, greater than the thickness of the structural body along the first direction.

Abstract: A control unit for a switching converter has an inductor element coupled to an input and a switch element coupled to the inductor element and generates a command signal having a switching period to switch the switch element and determine a first time period in which an inductor current is flowing in the inductor element for storing energy and a second time period in which energy is transferred to a load. An input current is distorted relative to a sinusoid by a distortion factor caused by current ripple on the inductor current. The duration of the first time period is determined based on a comparison between a peak value of the inductor current and a current reference that is a function of an output voltage of said voltage converter. A reference modification stage modifies one of the current reference and sensed value of the inductor current to compensate for distortion introduced by the distortion factor on the input current.
