IntelliFET® Low-Side Power Switches

Low Side IntelliFETs are self-protected MOSFETS where the load is switched with reference to ground. These parts integrate a power MOSFET with a complete array of protection circuits that guard against ESD, overcurrent, overvoltage, and overtemperature conditions. The integration of these protection functions therefore improves overall system reliability. The addition of features such as status flags also helps improve overall system performance by providing a diagnostics capability that aids the isolation and rectification of faults within a vehicle.

Our range of low-side IntelliFET self-protected MOSFETs are ideally suited for use in harsh environments where there is a need for immunity from radiated and conducted emissions. Consequently, self- protected MOSFETs are used in both automotive and industrial applications. Some of the functions IntelliFETs are deployed in are:

  • Remote I/O Controller Outputs (Programmable Logic Controllers)
  • Distributed I/O Modules
  • Relay Driving
  • Lamp Driving
  • Proximity Switches
  • Mechanical Relay Replacements
