DT
This pin selects the voltage multiplier circuit. If this pin is set to an “L” level, the voltage doubler
circuit is selected. If this pin is set to an "H" level, the voltage tripler circuit is selected. Do not
change the value of the setting after power is turned on.
V
C1
, V
C2
Capacitor connection pins for the voltage multiplier. Connect a 4.7
m
F capacitor between the V
C1
and V
C2
pins. If an electrolytic capacitor is used, connect the (+) side to pin V
C2
.
V
S1
Voltage doubler voltage output pin. This pin outputs the doubled voltage that has been input to
V
IN
. To increase stability of the power supply, connect a 4.7
m
F capacitor between this pin and V
SS
.
When using the doubled voltage, connect this pin and V
S2
.
V
S2
Voltage multiplier voltage output pin. Voltage multiplied by the factor specified by the DT pin
setting is output from this pin. When the voltage tripler is used, to increase stability of the power
supply, connect a 4.7
m
F capacitor between this pin and V
SS
. When using the voltage doubler,
connect this pin and V
S1
.
V
IN
Voltage multiplier voltage input pin. The doubled or tripled voltage input to this pin is output
from V
S2
.
V
2
, V
3A
, V
3B
LCD bias pins for segment drivers. These pins are connected to internal bias dividing resistors.
When using the ML9090-01 (at 1/4 bias), connect V
2
and V
3A
pins, and leave V
3B
unconnected
(open). When using the ML9090-02 (at 1/5 bias), connect V
3A
and V
3B
pins, and leave V
2
unconnected (open).
