UU642 Datasheet

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.
* After-wiping time: 2s~20s
* Interval pause: 4s~20s
* Wipe/wash mode priority
* Wiper motor’s park switch
* Relay driver with Z-diode
* One external capacitor determines all time sequences
* Interference protection according to VDE 0839 or ISO/TR 637/1
* Load-dump protected
