2. Functional Description
As a convenience feature of the windshield wiper, intermittent and wipe/wash opera-
tion functions are implemented in most of the automobiles. The U642B is a
cost-effective solution for an accurate timing function control. Wipe/wash mode has
priority over interval mode. Interval pause and after-wiping time can be set to fixed val-
ues by using resistors in a broad time range. Added value can be provided with an
individual, continuous adjustment of the interval pause by a potentiometer which may
be built into the stalk. For proper operation, it is mandatory to feed the signal of the
wiper motor's park switch into U642B.
