Rotation speed output pin (open-drain)
This output is held low at startup and when an abnormality is detected. In sensorless mode,
pulses are generated at 3 ppr according to the back-EMF.

IC.
Fin
This pin provides for thermal dissipation. Board traces should be designed, considering thermal
dissipation from the IC. (Since the fin and the package bottom are electrically connected, the Fin
pin should be connected to insulation or ground.)

per revolution.)
