LB1981V
No. 5917-7/9
Pin function
Motor counterelectromotive
voltage FG pulse pin.
Outputs a pulse using W
phase counterelectromotive
voltage as FG.
Connect to ground if not used.
Ground for all circuits except
output.
Coil waveform detect
comparator input pins.
Motor coil midpoint input pin.
Using this voltage as a
reference, the coil voltage
waveform is detected.
W phase coil output pin.
U phase coil output pin.
V phase coil output pin.
Output transistor ground.
Constant current drive is
performed by detecting the
voltage at this pin.
