VCREF
Control reference voltage applied
pin.
Determines control start voltage.
0V to VCC1
-1.5V

VC
Speed control voltage applied pin.
V type control technique
VC > VCREF : Forward
VC < VCREF : Slowdown
(Reverse-blocking circuit prevents
reverse rotation.)

UOUT
U-phase output.
23
RF
Upper side output NPN transistor
collector pin (common for all 3
phases).
For current detection, connect
resistor between VCC3 pin and RF
pin. Constant current control and
current limiter works by detecting
this voltage.
