ISL45041IRZ-T - Renesas Electronics
Description: 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 settin
