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
Relay activation can be controlled by a limit switch of the wiper motor or by a fixed activation period for systems without limit switch
Debounced input stages
Enable/disable of pre-wash delay by program pin
Polarity of WIWA:  VBatt
Polarity of INT:  VBatt
Relay output is protected with a clamping diode
