UU642中文资料INTERVAL AND WIPE/WASH  WIPER CONTROL IC数据手册UTC规格书

描述 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.
