ISL45042IRZ-T General Description

The V_COM voltage of an LCD panel needs to be adjusted to remove flicker. The ISL45042 can be used to digitally adjust a panel's V_COM voltage by controlling its output sink current. The output of the ISL45042 is connected to an external voltage divider and an external V_COM buffer amplifier. In this application, the user can control the V_COM voltage with 7-bit accuracy (128 steps). Once the desired V_COM 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 V_COM 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 ISL45042 is set using an external resistor connected to the SET pin. The full-scale sink current determines the lowest voltage of the external voltage divider. The ISL45042 is available in an 8 Ld 3mm x 3mm TDFN package with a maximum thickness of 0.8mm for ultra-thin LCD panel design.
