Datasheet Summary
Wiper Control for Intermittent and Wipe/ Wash Mode
Description
The U842B circuit is designed as an interval and wipe/ wash timer for automotive wiper control. The interval pause can be set in a range from 3 s to 11 s by an external 1-kW potentiometer. Wipe/wash mode has priority over the interval mode. The U842B controls the wiper motor with/without park switch signal. The integrated relay driver is protected against short circuits and is switched to conductive condition in the case of a load-dump. With only a few external ponents, protection against RF interference and transients (ISO/TR 7637-1/3) can be achieved.
