Function

Coil waveform detector comparator input

• Motor coil center tap input

• The LB1950V detects the coil voltage waveform taking

this voltage as the reference.

• W-phase coil output

• U-phase coil output

• V-phase coil output

• Output transistor ground

• The LB1950V implements fixed-current drive by

detecting the voltage on this pin.
