DRV2624: 1~2% in hundreds of thousands pcs failed auto calibration

Tool/software:

Hi Team,

After the following E2E exchange, my customer has produced their application with DRV2624.
DRV2624: DIAG_RESULT bit for calibration mode - Motor drivers forum - Motor drivers - TI E2E support forums

However they have seen 1~2% in hundreds of thousands pcs failed auto calibration.
The fail depends on specific LRA unit (part variation) and it seems the LRA unit with strong vibration tend to fail.

Could you advise how to deal with?

Best Regards,
Yaita
