Connect to MPU power pin V
The voltage specified according to liquid crystal cells is impedance-converted by
a split resistor or operational amplifier and applied.
The voltages need to be specified based on the V
relationship:
V
When power circuit turns on, the following voltages are applied to V
the internal power circuit.
Boosting capacitor positive connection pin. Capacitor is connected across
CAP1-pins.
CAP1+pins.
Boosting capacitor positive connection pin. Capacitor is connected across
CAP2-pins.
CAP2+pins.
Booster output. Capacitor is connected across V
Voltage regulator pin. Provides V
Operable only when the built-in resistor for V
