16 APPLICATION INFORMATION
16.1
General information
The required minimum value for the external capacitors in
an application with the PCF2119x are as follows: C
ext
for
V
LCD
and V
SS1,2
= 100 nF (min.), and for V
DD1,2,3
and
V
SS1,2
= 470 nF. Higher capacitor values are
recommended for ripple rejection.
For COG applications the recommended ITO track
resistance is to be minimized for the I/O and supply
connections. Optimized values for these are below 50
for the supply and below 100
for the I/O connections.
Higher track resistance reduces performance and
increases current consumption.
To avoid accidental triggering of power-on reset
(especially in COG applications), the supplies must be
adequately decoupled. Depending on power supply
quality, V
DD1
may have to be raised above the specified
minimum value.
When external V
LCD
is supplied, V
LCD2
should be left
open-circuit to avoid any stray current, and V
LCD1
must be
connected to V
LCDSENSE
