• Manufacturer Part Number: pt6584
• Description: Lcd Driver Ic - Princeton Technology Corp
• Manufacturer: Princeton Technology Corp.

LCD Driver IC
1/2 BIAS APPLICATION CIRCUIT
(FOR NORMAL PANEL USE)
Notes:
1. C t 0.047µF
2. Add a capacitor to the logic block power supply line so that the logic block power supply voltage
3. If the /RES pin is not used for system reset, it must be connected to the logic block power supply
4. The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1
