Features

* o Drives Backplane and Backlight o 4V to 30V Battery Voltage Range o Low 500µA Supply Current o Digital or Potentiometer Control of CCFL Brightness and LCD Bias Voltage o Negative LCD Contrast (MAX753) o Positive LCD Contrast (MAX754) o Independent Shutdown of Backlight and Backplane Sections o 25µA

Applications

* Both the backplane bias and the CCFL supply can be shut down independently. When both sections are shut down, supply current drops to 25µA. The LCD contrast and CCFL brightness can be adjusted by clocking separate digital inputs or using external potentiometers. LCD contrast and backlight brightnes
