Automotive Windshield Wiper Drive Reference Design
Description
This reference design drives a two-speed front windshield wiper: one or two rear wipers: and the pump: which sprays the front and back windshields in an automobile. In addition to controlling the brushed motors for the wipers and pump: this design includes inputs for wiper parking signals as well as diagnostic and protection features. Test data demonstrates the performance of the design with typical automotive wiper mechanisms: and complete design files can accelerate new project development for automotive designers.
