  • Patent number: 10917087
    Abstract: A circuit for controlling a first plurality of transistors connected in parallel and a second plurality of transistors connected in parallel, includes: a first plurality of stages, a respective one of the first plurality of stages being configured to supply a first control signal to a respective one of the first plurality of transistors; and a second plurality of stages, a respective one of the second plurality of stages being configured to supply a second control signal to a respective one of the second plurality of transistors. An output current of the respective one of the first plurality of stages is regulated based on a difference between a first value representative of a sum of output currents of each stage of the first plurality of stages and a second value representative of a sum of set points assigned to the first plurality of stages.

  • 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.
