Rear Wiper Interval/Wipe-Wash Control
U690B
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
D Time controlled interval/ wipe-wash
D Wiper arm’s park position control
D Interval pause typ. 7 s
D Dry wiping time typ. 4.4 s
D Multipurpose frequency comparator
D Relay driver with Z-diode
D RC-oscillator determines switching characteristics
D Debounced main signal input
D Power-on reset by low-voltage identification
D Protection according to ISO / TR 7637–1 (VDE 0839)
D Load-dump protection
Applications

Applications
Frequency Comparator
Speed Depending Switch with Hysteresis,
Figure 5
This circuit can be used to activate a load, such as a
warning lamp or buzzer via the relay (terminal A) at a
certain speed. The speed information is applied to signal
input, Pin 3, e.g. from Hall generator via terminal V.
It is compared in the integrated circuit with a reference
frequency created by the oscillator. The oscillator
frequency, f, is generated with external resistor, R2kR7,
and capacitor, C2.
If the frequency at Pin 3 is less than f/64, the relay control
ouput is deactivated.
If the frequency at Pin 3 is greater than f/64, the relay
control output is activated and at the same time the
hysteresis output, Pin 7, is disabled, the frequency is
reduced. This means Pin 7 supplies no current for
charging the capacitor, C2; therefore, R2 and C2 alone
define the oscillator frequency i.e., f [ R2@C2.
The hysteresis frequency is determined with the resistor,
R7.
Motor Speed Depending Switch with
Hysteresis, Figure 6
This circuit, figure 6, has the same function as the speed
with hysteresis mentioned above.
Information regarding motor speed (rpm) from the
ignition coil is delivered to signal input, Pin 3, via
terminal 1. Resistor values, R3 and R5 are so
dimensioned, that there is a peak voltage of nearly 3 V at
Pin 3 (from the ignition coil). Pin 4 is connected to GND,
so that there is a bypass for debouncing. In this way,
ignition pulse is supplied to frequency comparator.
