Output

• VSS6

This is a pin to connect the capacitor to store the doubled voltage. The capacitor of 0.1 mF or

more is connected between this pin and VDD.

• VSS2, 3

This is power pin to be used after the doubled voltage has passed through the regulator. They

provide the reference voltage used in the LCD bias voltage generator. The capacitor of 0.1 mF

is connected between this pin and VDD for electric charge distribution among capacitors and

voltage stabilization during generation of various types of LCD bias voltage.

• VC2, VCC2

These pins are used to connect the capacitors for electric charge distribution to generate LCD

bias voltage with reference to VSS2, 3.

They are connected with the capacitor of 0.1 mF.
