1. A magnetic field sensor system, comprising:
an anisotropic-magnetoresistive (AMR) magnetic field sensor configured to measure an externally applied magnetic field;
an overcurrent detection sensor comprising at least one AMR sensing element, the overcurrent detection sensor being configured to detect a presence of a high electrical current based on a measurement of the externally applied magnetic field; and
a cross-field detection sensor comprising at least one AMR sensing element, wherein the at least one AMR sensing element is arranged in a plane perpendicular to a sensing direction of the AMR magnetic field sensor.
