Windshield and Rearview Mirror Systems
Automotive windshield systems are rapidly evolving from the three basic functions: wipers, washers, and defrost. Silicon Labs’ C8051F5xx helps modernize these functions with features such as CAN, LIN or other serial networking to reduce wiring harness weight and cost as well as opening the design for new features, including efficient motor control for wiper and fluid pump motors which is especially important for vehicle electrification in mild hybrids with stop/start functionality and HEV/EVs.
The rearview mirror is becoming an increasingly complex system (compass, outside temperature, rain sensing, and glass dew point/condensation detecting). Silicon Labs’ Si114x is ideal for motion detection associated with rain on the glass, day or night. Coupled with the C8051F5xx MCU, the system provides the interface, control and data for rain detection, outside temperature, glass condensation, compass sensors and automated HVAC windshield defrost.
*Isolated drivers can be used when system noise needs to be reduced or minimized
