:
NEGATIVE POWER SUPPLY RAILS
The 2 supply rails V
SS1
and V
SS2
must be connected
together.
7.1.4
V
DD1
TO
V
DD3
:
POSITIVE POWER SUPPLY RAILS
V
DD2
and V
DD3
are the supply voltage for the internal
voltage generator. Both have the same voltage and may
be connected together outside of the chip. V
DD1
is used as
supply for the rest of the chip. V
DD1
can be connected
together with V
DD2
and V
DD3
but in this case care must be
taken to respect the supply voltage range
(see Chapter 13).
If the internal voltage generator is not used then V
DD2
and
V
DD3
must be connected to V
DD1
or connected to power.
7.1.5
V
LCDIN
: LCD
POWER SUPPLY
Positive power supply for the liquid crystal display.
An external LCD supply voltage can be supplied using the
V
LCDIN
pad. In this case V
LCDOUT
has to be left open-circuit
and the internal voltage generator has to be programmed
to zero. If the PCF8812 is in Power-down mode, the
external LCD supply voltage has to be switched off.
7.1.6
V
LCDOUT
: LCD
POWER SUPPLY
Positive power supply for the liquid crystal display. If the
internal voltage generator is used, the two supply rails
V
LCDIN
and V
LCDOUT
must be connected together. If an
external supply is used this pin must be left open-circuit.
7.1.7
V
LCDSENSE
:
VOLTAGE MULTIPLIER REGULATION
INPUT
(V

)
V
LCDSENSE
is the input of the internal voltage multiplier
regulation.
If the internal voltage generator is used then V
LCDSENSE
mustbeconnectedtoV
LCDOUT
.Ifaexternalsupplyvoltage
is used then the V
LCDSENSE
can be let open-circuit or
connected to ground.
