U6049B Datasheet | TEMIC Semiconductors

Radiator Fan Controlled Timer Description The bipolar integrated circuit, U6049B, is designed as a radiator fan controlled timer. After the ignition is switched off, the thermal switch of the engine can activate the radiator fan via relay for a preset period to support the cooling process. Features D D D D D Delay time range: 3.7 s to 20 h Cooling time starts when thermal switch is closed RC-oscillator determines switching characteristics Relay driver with Z-diode Debounced input for coolant temperature switch D Not debounced input for ignition key (Terminal 15) D Load-dump protection D RF interference protected D Protection according to ISO/TR 7637-1 (VDE 0839) Ordering...
