ISL45041
TFT-LCD I2C Programmable VCOM Calibrator
The VCOM voltage of an LCD panel needs to be adjusted to remove flicker. The ISL45041 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. an external source via
aThsetadnedsairredd2V-wCOirMe Is2eCttsinegriaisl
loaded from 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.
