ISL45042A
LCD Module Calibrator
The VCOM voltage of an LCD panel needs to be adjusted to
remove flicker. The ISL45042A can be used to digitally
adjust a panel’s VCOM voltage by controlling its output sink-
current. The output of the ISL45042A 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 ISL45042A 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 ISL45042A is available in an 8 Ld 3mmx3mm Thin DFN
package with a maximum thickness of 0.8mm for ultra thin
LCD panel design.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are 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.
