Abstract: Embodiments relate to integrated magnetic field sensor-controlled switch devices, such as transistors, current sources, and power switches, among others. In an embodiment, a magnetic switch and a load switch are integrated in a single integrated circuit device. In embodiments, the magnetic switch is configured to sense a dynamic change in magnetic field caused by movement of a magnet in at least one of a linear, three-dimensional, and rotational direction.

Abstract: A sensor device includes a first sensor element that generates a first sensor signal based on a varying magnetic field; a second sensor element that generates a second sensor signal based on the varying magnetic field; a signal processing circuit configured to generate a first pulsed signal based on the first sensor signal and generate a second pulsed signal based on the second sensor signal; a fault detector that detects a fault and generates an error signal indicating the fault; and an output generator that receives the error signal based on a first condition that the fault detector detects the fault, and simultaneously outputs a first output signal and a second output signal. In response to the first condition being satisfied, the output generator maintains the first output signal in a steady state and outputs the second pulsed signal as the second output signal.

Abstract: A power connector is provided that is configured to conduct a current. The power connector includes a base structure, an extension structure, and a connector head structure that define a current path for the current. The base structure is coupled to an output node of a primary conductor and receives the current from the primary conductor. The connector head structure is configured to output the current from the power connector to the load. The extension structure is coupled to and extends between the base structure and the connector head structure. The extension structure includes a current constriction region configured to increase a magnetic flux density of a magnetic field produced by the current flowing through the current constriction region at a position of a magnetic current sensor that generates a sensor signal based on the magnetic field magnetic field produced by the current flowing through the current constriction region.

Abstract: A power connector is provided that is configured to conduct a current. The power connector includes a base structure, an extension structure, and a connector head structure that define a current path for the current. The extension structure is coupled to and extends between the base structure and the connector head structure. The connector head structure includes a bore-hole that vertically extends into the connector head structure toward the base structure. The bore-hole is configured to receive a fastener for coupling the power connector to an electrical interface of a device. The connector head structure has a mechanical engagement feature configured to mechanically engage with a torque stabilization tool during a fastening of the fastener to the connector head structure in order to prevent a torque applied by the fastening of the fastener from being transferred to the extension structure.

Abstract: A current sensor arrangement includes a first conductor configured to conduct a first portion of a primary current in a current flow direction; a second conductor configured to conduct a second portion of the primary current in the current flow direction; and a magnetic sensor. The first and second conductor are coupled in parallel. The first current produces a first magnetic field as it flows through the first conductor and the second current produces a second magnetic field as it flows through the second conductor. The first conductor and the second conductor are separated from each other in a first direction that is orthogonal to the current flow direction, thereby defining a gap. The magnetic sensor is arranged in the gap such that the first conductor is arranged over a first portion of the magnetic sensor and the second conductor is arranged under a second portion of the magnetic sensor.
