(Note 1) VVO1+ = VVO1- = VPVCC1/2 [V] (Typ), VVO2+ = VVO2- = VPVCC1/2 [V] (Typ)
VVO3+ = VVO3- = (VPVCC2-0.7)/2 [V] (Typ),
VVO4+ = VVO4- = [ [(VPVCC2-0.7)/2 ] x 15.6 + VVCO x 20 ] / (15.6 + 20 ) [V] (Typ) at Hi-Z(M).
(Example) VVO4+ = VVO4- ≈ 2.53 [V](Typ) at VPVCC2=8[V],VVCO=1.65[V]

(2) Loading Driver
Only VCTL, FWD, and RVS terminal individually controls the load.
(This is not controlled by turning ON/OFF the MUTE123 and MUTE4 terminal)
It operates according to the truth table below.

(Note 2) VCTL (Pin18) is an arbitrary value of 0- REG5 (= 5.0[V]( Typ)).
(Note 3) VVO5+ = VVO5- = (VPVCC2-0.7)/2[V] (Typ) at Hi-Z(M).
(Note 4) VVO5+ = VVO5- = (VPVCC2-0.7)/2[V] (Typ) at M.
