  • Device for protecting loads supplied by an alternator
    Patent number: 6819535
    Abstract: A device of protection of at least one circuit supplied by a voltage obtained from at least one inductive element, including a switch for short-circuiting the supply provided by the inductive element, and circuitry for turning on the switch when the supply voltage exceeds a predetermined threshold and for turning it off when it is smaller than the threshold.
    Type: Grant
    Filed: November 13, 2002
    Date of Patent: November 16, 2004
    Assignee: STMicroelectronics S.A.
    Inventors: Philippe Merceron, Choukri Karoui
  • Integrated low-pass or band-pass filter
    Patent number: 6788168
    Abstract: A filter is formed as an integrated circuit by resistive and capacitive elements and includes, for connection to ground, at least two separate pads of a chip designed to be connected individually to at least two separate terminals of a package.

  • Integrated low-pass or band-pass filter
    Publication number: 20030001693
    Abstract: The invention concerns a filter produced in integrated circuit by means of resistive (R) and capacitive (C11, C12, C13, C14, C21, C22, C23, C24) elements and comprising, for ground connection, at least two separate bond pads (61-68) of a chip (69) not directly connected between them and designed to be connected individually to at least two separate terminals (71-78) of a housing (70).
