INTERVAL AND WIPE/WASH

WIPER CONTROL IC



DESCRIPTION

The bipolar integrated circuit UTC UU642 is designed as a

wiper for automotive application. It includes wipe, wash and

internal mode.

The UTC UU642 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

values 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 UTC UU642.


