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.
