com U2642B Intermittent- and Wipe/Wash Control for Wiper Systems Description With the U264xB, TEMIC Semiconductors developed a family of intermittent- and wipe/wash control circuits for windshield or backlite wiper systems with identical basic functions.
The circuit design provides the possibility to generate ”x” versions using different metallization masks.
Thus, it is easy to verify a broad range of time sequences which can be set independently of each other.
Features D Relay activation can be controlled by a limit switch of the wiper motor or by a fixed activation period for systems without limit switch D Debounced input stages D Enable/disable of pre-wash delay by progr...
