Abstract: An angle sensor may include a first angle measurement path to determine an angular position based on sensor values from a first set of sensing elements. The angle sensor may include a second angle measurement path to determine the angular position based on sensor values from a second set of sensing elements. A type of the second set of sensing elements is different from a type of the first set of sensing elements. The angle sensor may include a safety path to perform a set of safety checks, the set of safety checks including a first vector length check associated with the first angle measurement path and a second vector length check associated with the second angle measurement path. The angle sensor may include an output component to provide an indication of a result of the set of safety checks.

Abstract: Example implementations of the present disclosure relate to a vehicle, a fault monitoring device for a vehicle and a semiconductor device for detecting an overvoltage and/or an overcurrent. The semiconductor device includes a first die and a second die, which is configured to detect an overvoltage and/or an overcurrent in the electrical supply and/or communication of the first die. The semiconductor device also includes an output for outputting a signal, which indicates the overvoltage and/or the overcurrent.
