Abstract: A circuit includes a switching circuit including a first switch and a second switch. A current sensing circuit is coupled to the switching circuit to sense a first current through the first switch and to generate a first sensed current signal based on the sensed first current, and configured to sense a second current through the second switch and to generate a second sensed current signal based on the sensed second current. An output circuit is coupled to the current sensing circuit and is configured to generate a failure signal based on the first sensed current signal and the second sensed current signal.

Abstract: A semiconductor well of a non-volatile memory houses memory cells. The memory cells each have a floating gate and a control gate. Erasing of the memory cells includes biasing the semiconductor well with a first erase voltage having an absolute value greater than a breakdown voltage level of bipolar junctions of a control gate switching circuit of the memory. An absolute value of the first erase voltage is based on a comparison of a value of an indication of wear of the memory cells to a wear threshold value.

Abstract: A multi-phase electric motor includes a stator winding. The multi-phase electric motor is controlled by regulating a current flowing in the multi-phase electric motor in response to an applied voltage. An overload condition of the multi-phase electric motor is detected by monitoring a thermal increase of the value of a stator resistance of the stator winding of the multi-phase electric motor during a steady state condition of said multi-phase electric motor in which the current flowing in the motor has constant phase, and the motor is operating at constant load with constant speed.

Abstract: A converter circuit includes a half-bridge power circuit with a first and a second switch between an input node and a current node and between the current node ground, respectively. An inductor is coupled between the current node and an output node. Logic control circuitry is configured to switch the first and second switches to a current recirculation state and to a current charge state. The logic circuitry is configured to switch the switches from the current recirculation state to the current charge state as a result of a voltage indicator signal from an output voltage comparator being asserted while starting an on-time counter signal having an expiration value, and from the current charge state to the current recirculation state as a result of the on-time counter signal having reached its expiration value in combination with the voltage indicator signal from the voltage comparator being de-asserted.

Abstract: A method includes retrieving a plurality of datasets from respective memory registers of a memory and storing the retrieved plurality of datasets in respective register portions of a first register. A dataset of data-processing coefficients are stored in a second register. First processing is applied using, as the first operand, a first sub-set of dataset elements stored in the first register, and using, as the second operand, the data-processing coefficients, obtaining a first result. Second processing is applied using, as the first operand, a second sub-set of dataset elements stored in the first register comprised in a second window having a size equal to the dataset size, and using, as the second operand, the replica of the dataset of data-processing coefficients, obtaining a second result. An output is generated based on the first and second results. The first and second processing may perform multiply accumulate (MAC) operations.

Abstract: A device for monitoring breathing activity of, e.g., athletes while exercising includes a breathing activity sensor configured to be worn by a wearer and to provide a breathing activity signal indicative of the breathing activity of the wearer. A motion sensor is configured to be worn by the wearer and to provide a motion signal indicative of the motion activity of the wearer. A processing arrangement is coupled to the breathing activity sensor to process the breathing activity signal and produce a processed breathing activity signal. The processing arrangement includes filter circuitry having a first filtering bandwidth and a second filtering bandwidth. The first filtering bandwidth is larger than the second filtering bandwidth. The filter circuitry is coupled to the motion sensor and operates with one of the first filtering bandwidth and the second filtering bandwidth selected as a function of the motion signal from the motion sensor.
