Abstract
A sensor package includes a magnetic field sensor and a corruption detection and reset subsystem. The magnetic field sensor has a magnetic sense element and a ferromagnetic structure characterized by a baseline magnetic state. The subsystem includes a detector element, a processor, and current carrying structure positioned in proximity to the ferromagnetic structure. Methodology performed by the subsystem entails detecting at the detector element an altered magnetic state of the ferromagnetic structure, where the altered magnetic state differs from the baseline magnetic state. Methodology further entails determining, at the processor, when a reset action is needed in response to the altered magnetic state and applying a reset magnetic field to the ferromagnetic structure to reset the ferromagnetic structure from the altered magnetic state to the baseline magnetic state.
