(4)

Short brake

When 2.5V or more is applied to the short brake pin, the

top-side output transistors of all phases go off, and the

bottom-side output transistors go on. This applies brak-

ing to the motor. Short braking operates regardless of the

torque command signal.

(5)

Brake mode switching

When 2.5V or more is applied to the BR pin, the brake

mode for when EC > ECR can be changed.

(6)

Power save

When 2.5V or more is applied to the power save pin, all

circuits are on. When 1.0V or less is applied, the IC en-

ters power save mode, and functions only for surpressing

power consumption.
