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 PT6547 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 DOUT pin is an open-drain output and therefore needs a pull-up resistor. This resistor be
between 1K to 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.
