Automotive infotainment designers can upgrade to bigger, higher resolution displays with Maxim’s MAX20069.
The MAX20069 integrates four I2C-controlled, 150mA LED backlight drivers and a four-output thin-film-transistor liquid-crystal display (TFT-LCD) bias in a single chip.
The chip supports larger screen sizes and higher resolution by providing positive analogue supply voltage (PAVVD) and negative analogue supply voltage (NAVDD), both of which are required for low-temperature polysilicon panels (LTPS) that deliver higher resolution and lower cost than amorphous silicon panels.
The IC also supports the high currents that next-generation displays require, with 150mA per channel in the four-channel LED driver for 8-inch or larger displays and higher resolutions.
MAX20069 operates over the minus 40-degree Celsius to 105-degree Celsius ambient temperature range and is available in a 6mm x 6mm TQFN package.
