LC75808E, 75808W
Sample Application Circuit 4
1/9 duty, 1/4 bias drive technique (for use with large panels)
Note:
*
6.
Add a capacitor to the logic block power supply line so that the logic block power supply voltage V
DD
rise time when power is applied and the
logic block power supply voltage V
DD
fall time when power drops are both at least 1 ms, as the LC75808E/W is reset by the VDET.
If a variable resistor is not used for display contrast fine adjustment, the V
LCD
4 pin must be connected to ground.
If the function of the INH pin is not used, the INH pin must be connected to the logic block power supply V
DD
.
The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 k
to 10 k
) appropriate for the capacitance
of the external wiring so that signal waveforms are not degraded.
