1. Description

The U641B is a bi-polar integrated circuit designed for the wiper application in the

automotive market. It includes wipe, wash and internal mode.

U641B

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 U641B 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 the U641B.
