BD81842MUV-M
Automotive Panel Power Management IC
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. A Product Change Notice (PCN) is scheduled for this product.
While there will be no changes to electrical characteristics, certain specifications will be updated.
