About Infineon PROFET™ 12V high-side smart power switches

Infineon’s portfolio of high-side smart power switches for 12 V applications combines innovation, durability, and the performance to address diverse automotive needs. The Classic PROFET™ 12V family, built on over 15 years of proven technology, offers an RDS(on).range from 5–300 mΩ (0.2–20 A), delivering reliable performance across body, powertrain, transmission, and chassis applications, including fuel injection, brake control, and seat heating. PROFET™ + 12V enhances flexibility with advanced diagnostics, high energy robustness, and protection, offering pin compatibility with PROFET™ + 24V devices for seamless design scalability. PROFET™ +2 12V stands out with best-in-class efficiency, precise current sense accuracy, and ultra-low cranking voltage support, available in single, dual, and quad-channel options supporting automotive zone and body controller units. Finally, Power PROFET™ + 12V supports high-current loads up to 60 A with an ultra-low RDS(on) of 0.6 mΩ, making it ideal for replacing relays and fuses in power distribution applications, delivering unmatched efficiency and reliability under harsh conditions. Both families comes along with ISO 26262-ready certification.

Why to choose Infineon’s 12 V high-side switches

Infineon’s high-side smart power switches for 12 V applications offer cutting-edge features and benefits across diverse automotive systems. Key features include ultra-low RDS(on) (down to 0.6 mΩ) for high energy efficiency, advanced diagnostics, extensive protection (short circuit, overvoltage, overload, ESD, and temperature), and industry-leading current sense accuracy. Additional benefits include options for single, dual, and multi-channel devices, pin-to-pin compatibility across product families, low cranking voltage support, and compact, thermally efficient packages. These solutions enable smart and reliable power distribution, replacing relays and fuses to streamline system design and tackle capacitive load switching. Fully qualified for automotive standards, Infineon’s 12 V smart power switches ensure reliable operation even in harsh operations conditions.

Most of the products are ISO26262-ready and thus enable use in functional safety applications. Infineon’s 12 V high-side switches empower innovative, safe, and efficient power distribution in modern 12 V E/E architectures.

Ask the Smart Power Switches community

Infineon offers a range of design-in materials, which include application notes, evaluation boards, PCB design data, simulation models and also online simulations. Those materials could be found on the each product page in chapter "Design Support".  In addition, we offer a dedicated tool suite for Smart Power Switches and Gate Driver IC's for automotive power distribution.

Infineon Smart Power Switches & Gate Driver Tool Suite supports system architects and hardware designers from the idea to the realization. This suite allows the user to select the right smart power switch or gate driver IC for a specific load using one of the “Finder & Selection” tools. Together with the different “Simulation & Modeling” tools, various application scenarios can be simulated for the respective product. The results can be document in the report tool and verified with the “Configuration” tools plus the corresponding evaluation boards.
