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-µF 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-µF capacitor.
