Radiator Fan Controlled Timer
U6049B
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 Delay time range: 3.7 s to 20 h
D Cooling time starts when thermal switch is closed
D RC-oscillator determines switching characteristics
D Relay driver with Z-diode
D 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)
