The Classic PROFET™ Portfolio of Infineon is known as a very robust, solid solution to realize a high side architectures with semiconductors.


The key features are convincing and proven in the market:

  • High energy robustness
  • High voltage capability (58V)
  • Fast switching capability (up to 1kHz)
  • Low current consumption


PROFET™ intelligent power switches consist of DMOS power transistor and CMOS logic circuitry for complete built-in protection. The Classic PROFET™ family (PROtected FET) combines of a broad range of protected switches with different levels of smart features, like diagnosis (status or current sense) and protection features. In the event of a malfunction, the status feature is able to diagnose over temperature or open-load. The PROFET™ diagnostic features also provide the user with precise information about switch and load. Diagnostic feedback and load current sensing minimize risks by eliminating the need for additional discrete circuitry and assembly. This vast range of smart features makes the PROFET™ ideal for a variety of automotive (12 V), trucks & agriculture (24 V) and industrial applications.
