Function Description

— Power supply pins for logic. Apply the logic power supply voltage

from an external source.

— Power supply pins for booster circuit. Apply the booster circuit

power supply voltage from an external source.

— Ground pins for logic and driver circuit. Connect these pins to an

external ground.

— Power supply pins for driver. Output pins for internal booster

circuit.

Connect a 1-µ F capacitor for boosting between these pins and

the GND pins.

If not using the internal booster circuit, a direct driver power

supply can be input.

— These power supply pins are used to set the mode pins as fixed.

— These ground pins are used to set the mode pins as fixed.

— These are reference power supply pins for the LCD driver.

Connect a smoothing capacitor if an internal bias has been

selected.

— These are capacitor connection pins for the booster circuit.

Connect a 1-µ F capacitor.
