SLLSFH8A August 2021 – December 2021 MCT8316A
If the motor is spinning forward (same direction as the commanded direction) with sufficient speed (BEMF), the MCT8316A resynchronizes with the spinning motor and continues commutation by going directly to closed loop operation. By resynchronizing to the spinning motor, the user achieves the fastest possible start-up time for this initial condition. This resynchronization feature can be enabled or disabled through RESYNC_EN. If resynchronization is disabled, the MCT8316A can be configured to wait for the motor to coast to a stop and/or apply a brake. After the motor has stopped spinning, the motor start-up sequence proceeds as in Case 1, considering the motor is stationary.
