MAX20067GTJ/V+

    MAX20067 Automotive 3-Channel Display Bias IC with VCOM Buffer, Level Shifter, and I2C Interface Industry's First Integrated Power Solution for TFT-LCD with Synchronous Boost, Gate-Shading and I2C Description The MAX20067 IC is a complete TFT bias solution for automotive applications. It includes a current-mode boost converter and two push-pull charge-pump drivers. The IC also includes a gate-shading push-pull level shifter that can be used to improve display uniformity (when needed), and a DAC and VCOM buffer. All blocks on the IC can be used in stand-alone mode or through the I2C interface. Comprehensive control functions are included using the built-in I2C interface, as well as diagnostics and monitoring. The IC is intended to operate with 2.7V to 5.5V supplies. The MAX20067 is available in a 32-pin TQFN package and operates in the -40°C to +105°C temperature range.
