Infineon Technologies offers power IC manufacturing technology: SMART7. Infineon designed it specifically for automotive applications such as Body Control Modules or Power Distribution Centers. SMART7 power ICs drive, diagnose and protect loads in applications like heating, power distribution, air-conditioning, exterior and interior lighting, seat and mirror adjustment. They also provide a cost-effective and robust replacement of electromechanical relays and fuses. SMART7 is based on thin-wafer technology that reduces power losses and chip sizes. Based on SMART7, Infineon has introduced the two high-side power switch families PROFET+2 and High Current PROFET. The SPOC+2 multichannel SPI high-side power controllers will follow within a year.
The PROFET+2 family was developed for automotive 12 V lighting load applications and capacitive loads. These comprise e. g. halogen bulbs in external lighting control, interior lighting and dimming, as well as LED lighting. PROFET+2 devices provide state-of-the-art diagnostics and protection features. They maintain pin-out compatibility with their predecessor family PROFET+ for zero-cost migration. There is no ECU layout change needed, if single-channel devices are replaced by dual-channel variants and vice versa. Compared to their predecessor family, the PROFET+2 devices are up to 40 percent smaller in package size and improve energy efficiency with 50 percent lower current consumption. Their mass production is planned to start as of Q4 2017 and later. All high-side switches will be qualified in accordance with AEC Q100.
