Abstract: A current sensor arrangement includes a first conductor structure extending in a first direction and configured to carry a first current along the first direction; a second conductor structure extending in a second direction perpendicular to the first direction and configured to carry a second current along the second direction; and a magnetic field sensor arranged between the first conductor structure and the second conductor structure and configured to receive a first magnetic field produced by the first current and a second magnetic field produced by the second current. The first conductor structure and the second conductor structure overlap with the magnetic field sensor in a third direction that is perpendicular to the first and second directions. The magnetic field sensor includes a first sensor element sensitive to the first magnetic field and a second sensor element sensitive to the second magnetic field.

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: Transistor devices are provided. In some example implementations, a magnetic field sensor chip is fitted on a load electrode of a transistor chip. In other example implementations, two magnetic field sensors are arranged on a load electrode of a transistor chip in such a way that they measure different effective magnetic fields in the event of current flow through the transistor chip.
