(4) Short brake
When 3.5V or more is applied to the short brake pin, the
upper-side output transistors of all go off, and the lower-
side output transistors go on. Short braking operates re-
gardless of the torque command signal.
(5) Other circuits
When 3.5V or more is applied to the power save pin, all
circuits are on. When 1.5V or less is applied, the IC en-
ters power save mode. Also, the Hall bias pins turn on
and off with the power save pin.
