Note 1.
V
DD
and V
SS
are output pins stepped up internally. These pins should not be loaded directly.
2.
Capacitors C
1
to C
5
with a breakdown voltage of 20 V or higher are recommended. And it is recommended
to insert the capacitor that is 0.1

F to 1
μ
F between V
CC
and GND.
3.
If V
CHA
is kept low level (in 5 V mode), capacitor C
5
is not necessary.
4.
The pull-up resistors at driver input are active resistors.
