  • Patent number: 9523720
    Abstract: A multiple current sensor device or a multiple current shunt device includes at least two resistive sections comprising a first resistive section and a second resistive section, at least two connecting sections comprising a first connecting section and a second connecting section and a common connecting section. The first resistive section is electrically coupled in between the first connecting section and the common connecting section. The second resistive section is electrically coupled in between the second connecting section and the common connecting section. Using an embodiment may improve a trade-off between an efficient integration, a compact integration, a compact implementation and an accurate determination of at least one value indicative of at least one of multiple currents.

  • Patent number: 9504143
    Abstract: An electrical circuit includes a first circuit part and a second circuit part. A first electrical potential is applicable to the first circuit part, wherein a second electrical potential is applicable to the second circuit part. The two circuit parts are galvanically isolated from each other by an insulator, wherein the insulator includes a conducting portion. This conducting portion can be safely sensed by an additional circuitry, to detect if a full or partial contact to the first electrical potential or the second electrical potential has occurred due to a voltage shift or a current flow on the conducting portion, which is itself insulated. This sensing circuitry can incorporate protection elements to clamp voltages and limit currents to prevent destruction of connected circuitries in case of a fail of the insulation.

  • Publication number: 20160284990
    Abstract: In one embodiment, a method of forming a current sensor device includes forming a device region comprising a magnetic sensor within and/or over a semiconductor substrate. The device region is formed adjacent a front side of the semiconductor substrate. The back side of the semiconductor substrate is attached over an insulating substrate, where the back side is opposite the front side. Sidewalls of the semiconductor substrate are exposed by dicing the semiconductor substrate from the front side without completely dicing the insulating substrate. An isolation liner is formed over all of the exposed sidewalls of the semiconductor substrate. The isolation liner and the insulating substrate include a different material. The method further includes separating the insulating substrate to form diced chips, removing at least a portion of the isolation liner from over a top surface of the device region, and forming contacts over the top surface of the device region.
