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.

Features
  • Drives front and rear wiper motors
  • Drives bi-directional spray wash pump
  • Operates from 12-V automotive battery, with reverse battery and load-dump protection
  • On-board 3.3-V power supply and simple controller interface
  • This circuit design is tested and includes schematics, test data, and layout description.
