Claim Text:
1. A method for verifying measurements obtained from a hall effect sensor in a hall effect sensor system, the method comprising: exciting the hall effect sensor with an excitation current having a first value; obtaining 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; exciting the hall effect sensor with the excitation current having a second value, the second value different than the first value; obtaining 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; verifying operation of the hall effect sensor based at least on the first measurement and the second measurement; and detecting, by a microprocessor unit of the hall effect sensor system, faults or malfunctions within an analog front end included in the hall effect sensor system, the analog front end configured to receive, condition, and digitize the voltage output of the hall effect sensor.
