Pin function
GND pin for all circuits except output.
Control loop frequency compensator
pin.
Connecting a capacitor between this
pin and GND prevents closed loop
oscillation in current limiting circuitry.

Speed control voltage applied pin.
V type control technique
VC > VCREF : Forward
VC < VCREF : Slowdown
(Reverse-blocking circuit prevents
reverse rotation.)
W-phase output.
Output transistor GND.
V-phase output.
U-phase output.
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.
3 Hall FG/1 Hall FG select pin.
