ISL45042
LCD Module Calibrator
The VCOM voltage of an LCD panel needs to be adjusted to
remove flicker. The ISL45042 can be used to digitally adjust
a panel’s VCOM voltage by controlling its output sink current.
The output of the ISL45042 is connected to an external
voltage divider and an external VCOM buffer amplifier. In this
application, the user can control the VCOM voltage with 7-bit
accuracy (128 steps). Once the desired VCOM setting is
obtained, the settings can be stored in the non-volatile
EEPROM memory, which would then be automatically
recalled during every power-up.
The VCOM adjustment and non-volatile memory
programming is through a single interface pin (CTL). Once
the desired programmed value is obtained, the Counter
Enable pin (CE) can be used to prevent further adjustment
or programming.
The full-scale sink current of the ISL45042 is set using an
external resister connected to the SET pin. The full-scale
sink current determines the lowest voltage of the external
voltage divider.
The ISL45042 is available in an 8 Ld 3mmx3mm TDFN
package with a maximum thickness of 0.8mm for ultra thin
LCD panel design.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish,
which is RoHS compliant and compatible with both SnPb and Pb-free
soldering operations). Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
