1.4 1/3 DUTY 1/3 BIAS (FOR LARGE PANEL USE)

Notes:

1. A capacitor can be connected to the power supply line to make the power supply voltage VDD rise time (when power is applied) and the power

supply voltage VDD fall time power drops) are at least 1ms when PT6530 is reset via VDET.

2. If the /RES pin is not used to initiate the System Reset Function, it must be connected VDD.

3. The DO pin is an open-drain output and therefore needs a pull-up resistor. This resistor is between 1K and 10KΩ. The value of this resistor must be

in accordance with that capacitance of the external wiring so that the signal waveforms are in proper form.
