The PROFET™ family is Infineon's solution for power switch ICs. PROFET™ stands for protected MOSFET and gathers all High Side switches, whether they are automotive qualified or designed for the needs of industrial applications. PROFET™ intelligent power switches consist of DMOS power transistor and CMOS logic circuitry for complete built-in protection. They are highly integrated load switches and incorporate a broad range of smart features, including diagnosis and protection.
All PROFET™ sub-families offer protection against overload, overvoltage, short-circuit, excessive temperature, ground loss, power supply loss and Electrostatic Discharge (ESD). Additionally, depending on the applications they were designed for (automotive, industrial, consumer, transportation and commercial vehicles and more), the PROFET™ load switch subfamilies can also protect against dynamic overvoltage such as load dump and inductive load turn-off.
To answer all your needs in power switching, we designed several sub-families:

To answer all your needs in power switching, we designed several sub-families:
- PROFET™+2 12V, our latest product family and our best solution for current sensing. Designed for current from 1 to 21A, it offers one of the best accuracy for load monitoring (<5%) and design flexibility. Thanks for its tiny package (TSDSO-14), it insures a low power dissipation as well as space-saving on the PCB. PROFET™+2 is automotive qualified.
- Power PROFET™ is our solution for high-current applications, from 20 A to 40A. This integrated load switch family offers a high short circuit robustness as well as enhanced thermal capabilities thanks to its power package (DPAK, D²PAK and SSOP-24). Power PROFET™ is automotive qualified.
- PROFET™+ 12V drives current from 0.5A to 11A and diagnoses with current sense. It provides a high short circuit robustness and a load dump voltage of 42V. The whole product family is pin compatible, also with PROFET™+24V family. PROFET™+ 12V is automotive qualified.
- PROFET™+24V are designed to be used for trucks, buses, as well as construction & agriculture vehicles (CAV) in harsh environment. The scalable family (12 pin-compatible devices) offers comprehensive protection functions, very fast current sense diagnostic, an extended operating voltage range and high short-circuit robustness. PROFET™+ 24V is automotive qualified.
- Classic PROFET™ 12V is our most well-established and versatile family. With more than 20 years on the market, those power ICS have proven their technical advantages and benefits. Designed for currents from 0.5A to 20A, they have a low current limitation and a high-energy capability. They also operate on an extended voltage range and count not less than 6 different packages in the family. Classic PROFET™ 12V is automotive qualified.
- Classic PROFET™ 24V is the variation of the Classic PROFET™ but for 24V applications: commercial, agriculture and transport vehicles, ABS, fuel injection, etc. Additionally to the features and benefits of the 12V family, those integrated load switches also offer a high clamping voltage (up to 75V) and a high PWM capability (the highest: 100kHz). Available in 8 different packages, Classic PROFET™ 24V can drive up to 8 channels. Classic PROFET™ 24V is automotive qualified.
- Industrial PROFET™ were designed for targeting industrial applications. Due to their outstanding energy robustness, they are perfectly suitable for switching even higher inductive loads and driving relays. Their main application areas include high-voltage applications (VBAT up to 58 V), high-speed PWM applications (up to 1 kHz) and they are most notably capable of switching higher inductances smoothly. Industrial PROFET™ are also the perfect match for applications with long wiring or any other kind of inductive loads or applications with space constraints.
