HALL EFFECT SENSOR SYSTEM WITH DIAGNOSTIC CAPABILITIES

摘要

In a method for verifying measurements obtained from a hall effect sensor in a hall effect sensor system, the hall effect sensor is excited with an excitation current having a first value. A first measurement corresponding to a voltage output of the hall effect sensor when the hall effect sensor is excited with the excitation current having the first value is obtained. Additionally, the hall effect sensor is excited with the excitation current having a second value, the second value different than the first value. A second measurement corresponding to a voltage output of the hall effect sensor when the hall effect sensor is excited with the excitation current having the second value is obtained. Operation of the hall effect sensor is then verified based at least on the first measurement and the second measurement.
