Application Information (continued)
While the motor driver is enabled, the deassertion of ENABLEn initiates a stop-and-power-down sequence. This
sequence starts by disabling the motor (coasting) and waiting for rotation to stop. After rotation is stopped for 1 s
(as determined by the absence of transitions on HALLOUT), the internal circuitry is powered-down, the V5
regulator and power switch are disabled, and internal clocks are stopped.
After this stop-and-power-down sequence has been initiated (by deasserting the ENABLEn terminal for at least
1.2 μs), the sequence continues to completion, regardless of the state of ENABLEn. If ENABLEn is immediately
returned to the active state, the motor slows and stops for 1 s, then starts again.
