Description

The modern luxury side mirror includes many convenient features that allow for a better and safer experience for the driver beyond simple X-Y directional control of the mirror. This includes automatically dimming mirrors for glare reduction; mirror assembly folding to prevent damage in tight parking spaces; LED indicators for blind spot object detection: puddle lights and turn indicators; and heaters for defogging and deicing  the mirror in cold conditions. The addition of each of these features necessitates more electronics: so there is a desire from automotive electronics designers for multi-function integrated solutions that are also scalable as the load requirements change. This reference design provides a starting point for these types of electronics design considerations in a small form factor solution.
