SLLSFH8A August 2021 – December 2021 MCT8316A
The motor is commutated by detecting the zero crossing on the phase which is in Hi-Z state. If the motor is locked, the back-EMF will disappear and MCT8316A will be not able to detect the zero crossing. If MCT8316A is not able to detect zero crossing for LOSS_SYNC_TIMES number of times, LOSS_OF_SYNC event is recognized and action is taken according to the MTR_LCK_MODE. LOSS_OF_SYNC lock can be enabled/disabled by LOCK2_EN.
