Abstract: The present disclosure proposes a current sensor package with self-calibration functionality. No external microcontroller is needed. The current sensor package includes an integrated current sensor circuit configured to generate an analog sensor signal in response to an electrical current. The current sensor package includes an ADC coupled to the integrated current sensor circuit and configured to convert the analog sensor signal to a digital sensor signal. The current sensor package includes a digital processor coupled to the ADC and configured to implement/run a calibration procedure for the integrated current sensor circuit based on the digital sensor signal and predefined target values. The current sensor package includes a non-volatile memory coupled to the digital processor and configured to store the predefined target values and calibration parameters found during the calibration procedure.

Abstract: This disclosure concerns a sensor device including an electric conductor including a flat elongated shape. The electric conductor includes at least one cutout portion extending along the width of the electric conductor (200), the cutout portion extending from a first longitudinal side of the electric conductor towards an opposite second longitudinal side of the electric conductor, wherein a residual portion of the electric conductor remains between the cutout portion and the second longitudinal side of the electric conductor. A magnetic sensor is provided for measuring a magnetic field emanating from the electric current flowing through the electric conductor, wherein the magnetic sensor is arranged next to the electric conductor opposite the cutout portion.

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.
