Windshield wiper
A windshield wiper system has a significant impact on overall safety by providing a clear view to the driver. Increasing vehicle production worldwide and demand for new wiper technologies are driving the growth of the global automotive wiper market. The common windshield wiper motor control still remains with brushed DC motors. However, the BLDC motor type also offers advantages such as higher reliability, better size, and weight optimization.
Wipers have very specific requirements. Infineon´s integrated drivers, MOTIX™ motor control SoC products, provide cost-efficient solutions for a high-performance windshield wiper system. They offer intelligent power-saving modes including stop and sleep mode and supports energy management on demand (stand by). In addition, they address the demand for increased memory with 256KB flash (enables the customer to do a model-based software design). For wiping during cranking pulse, it is crucial to have low Vs operation. MOTIX™ 32-bit motor control SoC solutions can provide motor operation for low Vbatt operations. The last but not least, 14-bit sigma-delta ADC with TMR sensors enables the customer to have a cost solution and wiper angle precision at the same time.
Infineon offers a high variety of magnetic position sensors to optimize your windshield wiper design.
With the TLE5012 series based on GMR technology, Infineon provides a family of digital magnetic angle sensors that enable precise angle measurement as well as functional safety in accordance with an ISO 26262-ready development. The sensors have a small angular error of less than 1° over temperature and their entire service life. Dual-channel TMR bridge angle sensors, TLE5501 products, also meet your wiper design requirements and realize cost-efficient solutions with precise rotation sensing. For motor commutation, high-precision hall switches in a small package will be a perfect fit for your wiper design.
