IntelliFET® High-Side Power Switches

The High-Side IntelliFET is an automotive-compliant, intelligent high-side switch (IntelliFET).

It features a vertical DMOS MOSFET driver and integrated protection that include:

  • Overvoltage protection, including load dump
  • Overtemperature protection with auto restart
  • Reverse polarity protection
  • Short-circuit protection
  • ESD protection
  • Loss of ground protection
  • Voltage-dependent current limiting

The onboard diagnostics detect fault conditions and self-protection events, including open-load in the OFF-state, overload in the ON-state, and overtemperature shutdown. The devices include a diagnostic current-sense output (IS) proportional to load current and a defined diagnostic fault signal in case of overload operation, overtemperature, short-circuit, or open-load conditions.
