Classic HITFET™ 12 V Design Support
Infineon offers a range of design-in materials, which include application notes, evaluation boards, PCB design data, simulation models, and online simulations available on each product page in the "Design Support" section. In addition, we offer a dedicated tool suite for smart power switches and gate driver ICs for automotive power distribution.
Infineon smart power switches and gate driver tool suite support system architects and hardware designers from idea to realization. This suite allows the user to select the right smart power switch or gate driver IC for a specific load using one of the “Finder & Selection” tools. Together with the different “Simulation & Modeling” tools, various application scenarios can be simulated for the respective product. The results can be documented in the report tool and verified with the “Configuration” tools plus the corresponding evaluation boards.
