1 / 7 page 1 ® FN6189.4 ISL45041 TFT-LCD I2C 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 I2C 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 TDFN 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 AN1275 and “Ordering Information”.
