U846B Digital Wiper Control

The U846B is a bipolar integrated circuit for automotive use (“Rugged Silicon”) in interval and wipe/ wash control of windshield or backlite wipers. The interval pause can be set individually within a wide range by using a potentiometer. Wipe / wash mode with dry wiping activated either for 2 wipes .
