The highly integrated PROFET™ family (PROtected FET) incorporates a broad range of smart
features like diagnose and protection. PROFET™ intelligent power high side switches consist of a
DMOS power transistor and CMOS logic circuitry for complete built-in protection.
They offer protection against e.g. overload, overtemperature, short circuit for all kinds of automotive and industrial applications.
The well established high side switch family Classic PROFET
TM is designed for targeting a variety of automotiv applications which include all
types of resistive, inductive and capacitive loads. Due to their outstanding energy robustness,
they are perfectly suitable for switching even higher inductive loads(high side switches). Their
main application areas include high-voltage applications (v
BAT up to 58 V), high speed PWM applications (up to 1kHz) and they are most notably
capableof switching higher inductans smoothly.
The Classic PROFET TM device concept includes protection against short circuit, overvoltage and overload. The implemented diagnostic features offer the choice of either status or current sense features for screening the load status and detecting a potential failure mode.
Infineon launches its next generation of discrete smart high side switches - PROFET
TM+. The family is designed to drive light bulbs and LEDs in the harsh environment but
can also be used for industrial applications.
The high side switch devices provide state-of-the-art diagnostic features. Their high current sense accuracy (kILIS) is able to diagnose even the smallest loads, such als LEDs. The very high short-circuit robustness across the whole family sets the market benchmark. Infineon is the first comapny to specifythe short-circuit robustnessof a devicein the datasheet. 100k cycles SC robustness (PROFET TM +12V) is a factor 200 improvement towards today´s smart high side switches in the market.
