Power PROFET™ is a benchmark family of ultra-low ohmic protected high-side switches (1.0mΩ to 2.5mΩ) with integrated protection functions and diagnostics for automotive and 12V industrial markets.

The devices are especially designed to drive high current loads of 25 to 40A DC and to replace high current relays and fuses in a wide range of applications such as power distribution and heating.

Power PROFET™ switches are also an ideal driving solution for an increasing number of applications with high switching cycle requirements.
