Automotive Panel Power Management IC - BD81842MUV-M
The BD81842MUV-M is a power management IC for TFT-LCD panels which are used in car navigation, in-vehicle center panel, and instrument cluster. Incorporates high-power FET with low on resistance for large currents that employ high-power packages, thus driving large current loads while suppressing the generation of heat. A charge pump controller is incorporated as well, thus greatly reducing the number of application components. Also Gate Shading Function is included.
