Patent number: 7518354Abstract: An electronic circuit includes a first substrate having a first substrate surface and a device supported by the first substrate surface. The device is selected from among a passive electronic component and an active electronic component. The electronic circuit also includes a second substrate having a second substrate surface and a conductor proximate to the second substrate. The electronic circuit also includes a magnetic field transducer disposed over the conductor and coupled to the device and an insulating layer disposed between the conductor and the second substrate. The conductor is adapted to carry an electrical current to generate a first magnetic field. The electronic circuit is responsive to the first magnetic field. In some embodiments, the conductor is a secondary conductor and the circuit further includes a primary conductor disposed proximate to the magnetic field transducer and an insulating layer disposed between the primary conductor and the second substrate.Type: GrantFiled: June 25, 2007Date of Patent: April 14, 2009Assignee: Allegro Microsystems, Inc.Inventors: Jason Stauth, Richard Dickinson, Glenn Forrest, Ravi Vig

Patent number: 7368904Abstract: A proximity detector includes a fine DAC and a coarse DAC, outputs of which are summed to provide a tracking signal for tracking a magnetic field signal. The proximity detector provides two mode of operation. In a first mode of operation the coarse and fine DACs operate in combination as one higher order DAC. In a second mode of operation, the coarse DAC is provided with one or more extra counts, allowing the tracking signal to move more rapidly to track a rapidly changing magnetic field signal. In another embodiment, the proximity detector also includes an offset circuit for bringing at least one of the magnetic field signal and the tracking signal towards the other one of the magnetic field signal and the tracking signal.Type: GrantFiled: February 12, 2007Date of Patent: May 6, 2008Assignee: Allegro Microsystems, Inc.Inventors: Karl Scheller, Gerardo Monreal, Jason Stauth

Patent number: 7259545Abstract: An integrated sensor includes a magnetoresistance element electrically coupled to a device disposed on or integrated in a silicon substrate. A conductor is provided proximate to the magnetoresistance element. The integrated sensor can be used to provide various devices, such as a current sensor, a magnetic field sensor, or an isolator. Further, the integrated sensor can be used in an open loop configuration or in a closed loop configuration in which an additional conductor is provided. The magntoresistance element may be formed over the silicon substrate or on a separate, non-silicon substrate. Also described is an integrated sensor comprising a substrate, a magnetic field transducer disposed over a surface of the substrate, and a conductor disposed over the surface of the substrate proximate to the magnetic field transducer. The magnetic field transducer can be a Hall effect transducer or a magnetoresistance element.Type: GrantFiled: February 11, 2003Date of Patent: August 21, 2007Assignee: Allegro Microsystems, Inc.Inventors: Jason Stauth, Richard Dickinson, Glenn Forrest, Ravi Vig
