PT6554

Notes:

1. A capacitor must be added to the power line so that both the power supply voltage

(VDD) rise time when power is applied and the power supply voltage (VDD) fall time

when power drops are at least 1 ms.

2. DO is an open-drain output and requires a pull-high resistor between 1kΩ to 10kΩ.

The pull-up resistor value must be appropriate to the capacitor of the external writing so

that the signal wave forms are not degraded.

3. R1=R2=R3, the resistance value must be decide by the LCD panel size.
