Rear Window Heating Timer
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
Delay time range: 3.7 s to 20 h
RC oscillator determines switching characteristics
Relay driver with Z-diode
Debounced input for toggle switch
Two debounced inputs: ON and OFF
Load-dump protection
RF interference protected
Protection according to ISO/TR7637-1 (VDE 0839)
U6046B: Inputs switched to V
Batt
U6047B: Inputs switched to ground
