HITFET™ Smart Low-Side Switches

Infineon HITFET™ Smart Low-Side Switches are versatile power transistors ideally designed for automotive and industrial applications. Their built-in intelligence and protective features offer improved performance & reliability over conventional, discrete solutions. The HITFET Smart Low-Side Switches provide a higher level of protection with overtemperature, short circuit, overcurrent, overvoltage, and ESD. Infineon HITFET combines all these protection features in one easy-to-use device.
