U6046B / U6047B
Description
The window heating timers are bipolar integrated
circuits. Due to time controlled functions, they reduce the
current consumptions of high loads i.e., heating resistors.
An ON-relay can be switched off after a preset delay time.
The relay time can be interrupted manually, whereas a
retrigger function is not provided.
Features
D Delay time range: 3.7 s to 20 h
D RC oscillator determines switching characteristics
D Relay driver with Z-diode
D Debounced input for toggle switch
D Two debounced inputs: ON and OFF
D Load-dump protection
D RF interference protected
D Protection according to ISO/TR7637-1 (VDE 0839)
D U6046B: Inputs switched to VBatt
D U6047B: Inputs switched to ground

U6046B / U6047B
WFigure 11 shows the input circuit of U6047B. It has an
integrated pull-up resistance (100 k ), RF capacitor
(15 PF) and Z-diode (7 V). The circuit reacts to voltages
less than 2 V. The external protective resistance has a
Wvalue of 2 k and the push-button switch is connected to
GND. Contact current, I, is calculated as follows:

WIt can be increased by connecting a 5.6 k resistor from
the push-button-switch to VBatt as shown in figure 19.
The connecting diodes prevent the current flow to the
input of the Z-diodes when the rocker actuated-switch is
in open-state (current-consumption only in
standby-mode). If necessary, these diodes can be omitted.
