Gate Driver ICs for External MOSFETs
The trend towards greater eiciency in automotive
applications also applies to electric motors. Applications
such as power steering, HVAC compressors and engine
cooling fans will be controlled by electronic motors in the
future. Infineon’s family of configurable, H-Bridge and
3-phase gate driver ICs can be combined with MOSFETs to
provide the power and eiciency these systems demand.
