Part Number : U842B-FP
Function : Wiper Control for Intermittent and Wipe / Wash Mode
Package : DIP, SO 8 Pin type
Maker : Temic Semiconductors
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-kpotentiometer. 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 components, protection against RF interference and transients (ISO/TR 7637-1/3) can be achieved.
1. Interval input: low side
2. Wipe/ wash input: low side
3. Park input: high side (park position)
4. Output driver protected against short circuit
5. All time periods determined by RC oscillator
6. Fixed relay activation time of 500 ms
