Rear Wiper Interval/Wipe-Wash Control
Description
The bipolar integrated circuit, U690B, is designed with a
time coded input for the rear pane wiper application. The
length of the input signal determines the mode of
operation i.e., intermittent or wipe/ wash; therefore, only
one signal line is sufficient from the input switch to the
electronic module.
Features
Time controlled interval/ wipe-wash
Wiper arm’s park position control
Interval pause typ. 7 s
Dry wiping time typ. 4.4 s
Multipurpose frequency comparator
Relay driver with Z-diode
RC-oscillator determines switching characteristics
Debounced main signal input
Power-on reset by low-voltage identification
Protection according to ISO / TR 7637–1 (VDE 0839)
Load-dump protection
Applications
Speed or R.P.M. detection
