Note1 : When the input voltage to the IC pin is set with the resistor dividing reference voltage such as VREF,
make sure not to use “VC1”, “VC2” and “VC3”, together with the voltage-dividing resisters.
(In any mode other than shutter mode, the IC pin discharge transistor inside the IC pin switches to ON.)
Note2 : The above block diagram applies to LB8653FN. For the LB8653T, a single pin is provided for VB, VCC,
PGND, SGND, OUT7 and OUT8 respectively.
