LC75844M Datasheet, PDF (13/14 Pages) Sanyo Semicon Device – 1/4 Duty General-Purpose LCD Driver

Sample Application Circuit 3
1/3 Bias (for use with normal panels)
LC75844M
General-purpose
output ports
Used for functions
such as backlight
control
C ≥ 0.047 µF
From the
microcontroller
Note: *2 When a capacitor except the recommended external capacitance (C_OSC = 680 pF) is connected the OSC pin, we recommend that applications
connect the OSC pin with a capacitor in the range 220 to 2200pF.
