Datasheet U6046B DatasheetU6046B Datasheet (PDF)

U6046B / U6047B 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 D D D D D Delay time range: 3.7 s to 20 h RC oscillator determines switching characteristics Relay driver with Z-diode.
