Rear Window Heating Timer
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
