UU642

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. 

FEATURES
