C Programmable VCOM
Calibrator
The VCOM voltage of an LCD panel needs to be adjusted to
remove flicker. This part provides a digital interface to control
the sink-current output that attaches to an external voltage
divider. The increase in output sink current lowers the
voltage on the external divider, which is applied to an
external VCOM buffer amplifier. The desired VCOM setting
is loaded from an external source via a standard 2 wire I

C
serial interface. At power up the part automatically comes up
at the last programmed EEPROM setting.
An external resistor attaches to the SET pin, and sets the
full-scale sink current that determines the lowest voltage of
the external voltage divider.
The ISL45041 is available in an 8 Ld 3mm x 3mm Thin DFN
package with a maximum thickness of 0.8mm for ultra thin
LCD panel design.
An evaluation kit complete with software to control the DCP
from a computer is available. Reference Application note

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.
