PRODUCTION DATA
This diagnostic mechanism allows the controller to check if the offset of the Hall sensor is within the factory-determined limits and the offset cancellation circuitry is working properly.
To run this check, the controller must enable the check and set the scheduling for the run. During this check, the AFE is not available for magnetic field conversion. The user can configure the ALERT pin to toggle if an error is detected. This error is also reported in the user register.
Run Mode | Every time a magnetic measurement is initiated and completed |
Configuration Register(s) | DIAG_EN to enable test. DIAG_SEL to schedule when the test is run |
Fault Register Bit | SENS_STAT |
Impact if disabled | If disabled, any failures with offset cancellation mechanism or large drift of Hall-effect sensor may not be detected, leading to potentially incorrect magnetic field conversion. |
