Control reference voltage input
The control start voltage is determined by
this voltage.

Speed control voltage input
This IC implements a voltage control
system in which VC > V
CREF
means
forward rotation and VC < V
CREF
means
slow foward rotation.
(This IC includes reverse rotation
prevention circuit, so reverse rotation will
not occur.)

Peak hold circuit capacitor connection.
Connect a capacitor to this pin to smooth
