  • Publication number: 20200285259
    Abstract: A voltage regulator circuit includes a first voltage regulator having a first output voltage selection pin set and producing a first output voltage based on a first digital signal received at the first output voltage selection pin set, and a second voltage regulator having a second output voltage selection pin set and producing a second output voltage based on a second digital signal received at the second output voltage selection pin set. The first and second voltage regulators are operable in a voltage tracking mode with the output voltage of the second voltage regulator tracking the output voltage of the first voltage regulator when digital signals received at the selection pin sets have a same value. An overvoltage sensor detects overvoltage events at the first voltage regulator. Control circuitry selectively avoids operation in voltage tracking mode as a result of an overvoltage event detected at the first voltage regulator.

  • Publication number: 20200112164
    Abstract: A circuit includes processing circuitry is sensitive to a regulated voltage at the output node and to a temperature of the circuit. The processing circuit is configured to provide voltage and temperature sensing signals indicative of the regulated voltage at the output node and the temperature of the circuit. The processing circuitry is configured to assume i) a first state, as a result of the voltage sensing signal reaching a voltage threshold, ii) a second state, as a result of the temperature detection signal reaching a temperature threshold, or iii) a third state, as a result of both the voltage and the temperature sensing signals failing to reach the thresholds. The circuit comprises a warning output coupled to a warning signal generation network controlled by the processing circuitry.

  • Patent number: 8338049
    Abstract: A microfluidic system through which a solution of at least an oxidable compound is fed to a feed manifold of an energy converting electrochemical device includes a flow connector. The flow connector includes a silicon platform having a bottom side and an opposing top side, and through holes extending therethough. The silicon platform includes first and second channels defined on the bottom side for communicating with the through holes. The second channel forms an inlet for the feed manifold of the energy converting electrochemical device when the bottom side of the silicon platform is coupled to a flat coupling area of the device. A micropump module is coupled to the top side of the silicon platform for communicating with the through holes in the first and second channels. First and second supply cartridges are coupled to the top side of the silicon platform for communicating with the through holes in the first channel.

  • Patent number: 7906874
    Abstract: A managing method of the start-up phase of at least one micro fuel cell to be connected to a load includes: measuring a micro fuel cell voltage value across the micro fuel cell activated by means of a fuel injection; comparing the micro fuel cell voltage value with a first threshold voltage value; and establishing an operation mode of the micro fuel cell as follows: as long as the micro fuel cell voltage value is lower than the first threshold voltage value, the micro fuel cell operates in a first open circuit state, during which it is not connected to the load; when the micro fuel cell voltage value overcomes the first threshold voltage value, the micro fuel cell passes to a second pre-ignition state, during which it supplies a current value corresponding to the first threshold voltage value, according to a static voltage-current characteristic of the micro fuel cell.
