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 (when power drops) are at least 1ms when PT6583 is reset via VDET. 2. If the /RST Pin is not used to initiate the System Reset Function, it must be connected to VDD. 3. The DO Pin is an open-drain output and therefore needs a pull-up resistor. This resistor must be between 1k to 10k Ohms. The value of this resistor must be in accordance with that the capacitance of the external wiring so that the signal waveforms are in proper form. 4. C>0.047uF
