PROFET+ Family - Smart High-Side Switches

Infineon PROFET iconThe new PROFET™+ Family delivers easy plug and place modularity between single- and dual-channel discrete Smart High-Side Switches.

PROFET™+ contains three single-channel devices with 30, 45 and 90 mΩ RDS(on) and is specifically designed to drive light bulbs and LEDs in the harsh automotive environment. The devices provide state-of-the-art diagnostics and protection features. Their high current sense accuracy enables them to diagnose even the smallest loads such as LEDs. The family's very high short circuit robustness is a benchmark in the market. All family members have an identical feature set – once you know one device, you know them all.

The new single-channel devices in the small DSO8 exposed pad package have the same small footprint as dual-channel family members in the DSO14 exposed pad package (2x20-180 mΩ). This modularity gives engineers maximum design flexibility to change loads and devices without having to make major modifications to board layout.

The complete PROFET™+ family will range from 8...180 mΩ RDS(on).

PROFET+ Family Key Features

  • N-channel MOSFET with charge pump
  • Voltage dependent current limitation
  • Overtemperature protection with auto-restart
  • Very high robustness against repetitive short circuit (100 k cycles)
  • Highly accurate proportional load current sense for diagnostic feedback of smallest loads (LEDs)
  • PWM capability up to 200 Hz for bulbs and 400 Hz for LEDs
  • Very low standby current (<0.5 µA)
  • Pin compatibility in PG-DSO14 and PG-DSO8 exposed pad packages
  • RoHS & ELV compliance

Key Applications

  • 12 V grounded high-side loads from 5 A down to 0.5 A (permanent/channel)
  • Qualified for automotive applications such as lighting, body control modules, heating, energy/power distribution
  • Various industrial applications
  • Capacitive loads such as bulbs, lamps with high inrush currents or LEDs with low currents
  • Resistive loads such as heating streamers
  • Inductive loads such as electromagnetic valves
  • “Electronic” loads such as control unit power supplies
  • Replacement of electromechanical relays, fuses and discrete circuits
