Note: *8.Add a capacitor to the power supply line so that the power supply voltage VDD rise time when power is applied and the power supply voltage VDD

fall time when power drops are both at least 1 ms, as the LC75853NE/NW is reset by the VDET.

*9.The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 to 10 kΩ) appropriate for the capacitance of the

external wiring so that signal waveforms are not degraded.

No. 4967-19/24
