Control reference voltage supply
pin. Determines control start
voltage.
Speed control voltage supply 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
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.
When this pin is connected to GND,
the limiter setting current is
increased by a factor of 1.5.
Short brake pin
BRAKE:
High –> Short brake operation
Low/Open –> Motor drive operation
