Publication number: 20240103046Abstract: A pre-driving stage drives one or more Field Effect Transistors in a power stage driving a load. A method for measuring current flowing in the Field Effect Transistors includes: measuring drain to source voltages of the one or more Field Effect Transistor; and measuring an operating temperature of the one or more Field Effect Transistor. The current flowing in the Field Effect Transistors is measured by: calculating the respective on drain to source resistance at the operating temperature as a function of the measured operating temperature and obtaining the current value as a ratio of the respective measured drain to source voltage over the calculated drain to source resistance at the operating temperature.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Applicant: STMicroelectronics S.r.l.Inventors: Placido DE VITA, Salvatore ABBISSO, Giovanni Luca TORRISI, Antonio Davide LEONE

Patent number: 11372435Abstract: 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.Type: GrantFiled: February 28, 2020Date of Patent: June 28, 2022Assignee: STMicroelectronics S.r.l.Inventors: Giovanni Luca Torrisi, Salvatore Abbisso, Cristiano Meroni

Patent number: 11211783Abstract: 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.Type: GrantFiled: September 30, 2019Date of Patent: December 28, 2021Assignee: STMICROELECTRONICS S.R.L.Inventors: Giovanni Luca Torrisi, Salvatore Abbisso, Cristiano Meroni
