  • Patent number: 10283699
    Abstract: A coupler is disclosed that employs hall-effect sensing technology. Specifically, the coupler is configured to produce an output voltage by converting the magnetic field generated by a current conductor at an input side. The output and input sides may be electrically isolated from one another but may be coupled via the hall-effect sensing technology, such as a hall-effect sensor. The output and input sides may be provided in an overlapping configuration.

  • Patent number: 9960671
    Abstract: A capacitive isolation system, capacitive isolator, and method of operating the same are disclosed. The capacitive isolation system is described to include a first semiconductor die and a second semiconductor die each having capacitive elements established thereon and positioned in a face-to-face configuration. An isolation layer is provided between the first and second semiconductor die so as to establish an isolation boundary therebetween. Capacitive coupling is used to carry information across the isolation boundary.

  • Patent number: 9520354
    Abstract: An isolation system, isolation capacitor, and Integrated Circuit are disclosed. The isolation capacitor is described to include a first capacitive element, a second capacitive element, a primary isolation layer positioned between the first and second capacitive elements, as well as a secondary isolation layer positioned between the first and second capacitive elements. The secondary isolation layer has an area that is larger than an area of one or both of the first and second capacitive elements, thereby reducing the likelihood of breakdown between the first and second capacitive elements.

  • Patent number: 9279946
    Abstract: An optoelectronic device is disclosed. The optoelectronic device may be employed as a single or multi-channel opto-coupler that electrically isolates one circuit from another circuit. The opto-coupler may include one or more premolded cavities with a light-coupling medium contained therein. Walls of the one or more premolded cavities advantageously help shape the light-coupling medium during manufacture, therefore, resulting in a light path with controlled shape and dimensions.
