1 / 8 page 1 ® FN6158.2 ISL45042A LCD Module Calibrator The VCOM voltage of an LCD panel needs to be adjusted to remove flicker. The ISL45042A can be used to digitally adjust a panel’s VCOM voltage by controlling its output sink- current. The output of the ISL45042A is connected to an external voltage divider and an external VCOM buffer amplifier. In this application, the user can control the VCOM voltage with 7 Bit accuracy (128 steps). Once the desired VCOM setting is obtained, the settings can be stored in the non-volatile EEPROM memory, which would then be automatically recalled during every power-up. The VCOM adjustment and non-volatile memory programming is through a single interface pin (CTL). Once the desired programmed value is obtained the Counter Enable pin (CE) can be used to prevent further adjustment or programming. The full-scale sink current of the ISL45042A is set using an external resister connected to the SET pin. The full-scale sink current determines the lowest voltage of the external voltage divider. The ISL45042A is available in an 8 Ld 3mmx3mm Thin DFN package with a maximum thickness of 0.8mm for ultra thin LCD panel design.
