com U846B Digital Wiper Control for Intermittent and Wipe/ Wash Mode Description 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 or for a certain time has priority over the interval mode.
The U846B is used in applications to control wiper motors with or without park-switch signal feedback.
The integrated relay driver is protected against short circuits and is switched to conductive condition in the case of a load-dump.
By using only a few external components, protection against RF interference and ISO transients can be achieved.
* * Features D Interval input: high side D Wipe/ wash input: high side D Park input: low side (park position) D Output driver protected against short circuits D All time periods determined by an RC-oscillator D Typical relay activation time of 500 ms D Adjustable interval pause from 1.
2 s to 27 s D Typical pre-wipe delay of 100 ms D Dry wiping D – With park-switch signal: 2 cycles D – Without park-switch signal typically 5.
25 s D Inputs INT, WASH and PARK digitally debounced D All inputs with integrated RF protection D Load-dump protection and interference protection according to ISO 7637–1/4 (DIN 40839) Application Digital interval / wipe/ wash control for windshield or backlite wiper motors with a 22-kW potentiometer (typical value) for interval pause adjustment.
Recommended oscillator circuitry: R6 = 36 kW ; C2 = 100 nF.
