Infineon's HITFET (high-integrated temperature protected FET) family provides a higher-level of protection with over-temperature, short circuit, overcurrent, overvoltage, and ESD. HITFET combines all these protection features in one easy-to-use device. These low-side switches are versatile power transistors ideally designed for automotive and industrial applications such as interior light dimming and relay driving. Their built-in intelligence and protective features offer not only significant cost and PCB reduction, shorter time to market, but also improved performance and reliability over conventional, discrete solutions.

HITFET low-side power switches represent a unique, new generation of smart transistors for an almost unlimited range of automotive and industrial applications, distinguished by all around protection against:

• Short circuits and overloads
• Voltage surges (or open circuit)
• Excess temperature
• Electrostatic discharge (ESD)

Additionally, the HITFET family provides fault detection and diagnostic via a feedback loop system.
