Small, Efficient, Flexible: Meet the New Body Control Module Challenges with the Infineon’s Smart Switches

The Body-Control-Module is getting more and more complex. From pure turning on and off the loads to master the unit for multiple functions like exterior and interior lighting, comfort feature like seat heating. To enable such high integration on one ECU also the power switches must become smaller - and smarter!

A scalable portfolio of protected switches on one hand and a portfolio handling simple parallel inputs with a serial interface like SPI on the other hand will manage the new BCM challenges for switches.


Therefore Infineon invented the most scalable PROFET™+2 family and the integrated SPI-Power-Controller SPOC™+2 in their 5th generation.

Small relays and LEDs which are located on the BCM can be driven by the latest multichannel portfolio SPIDER+.


The HITFET™+ family (High Integrated Temperature protected MOSFET) provides a compelling feature-set with its diagnosis function, digital status feedback, short circuit robustness, and controlled slew rate adjustment for easily balancing switching losses and EMC compliance.

Beside pure switch solutions Infineon provides a range of highly integrated System Basis Chips (SBC) for more functions and less space. AURIX™ multicore even allows you to integrate two applications in one device: BCM and gateway. Benefits included enhanced communication with lower power consumption and a selection of top security features.

Key Product Families:
