V
DD2
and V
DD2_HV
are the supply voltages for the internal voltage generator. Both have to be on the same voltage and
may be connected together outside of the chip. If the internal voltage generator is not used, they should be both
connected to ground. V
DD1
is used as power supply for the rest of the chip. This voltage can be a different voltage than
V

POWER SUPPLY
Positive power supply for the liquid crystal display. If the internal voltage generator is used, the two supply rails
V
LCD1
and V
LCD2
must be connected together. An external LCD supply voltage can be supplied using the V pad. In this
case, V
LCD1
has to be connected to ground, and the internal voltage generator has to be programmed to zero. If the
PCF8549 is in power-down mode, the external LCD supply voltage has to be switched off.
