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 3mmx3mm TDFN
package with a maximum thickness of 0.8mm for ultra thin
LCD panel design.
