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)

Figure 7. Timing waveform
The programming input (Pin 5) is high-ohmic and should
therefore be connected to Pin 7 (Vstab) or GND. The relay
control output is shown according to Pin 5 connection.
Thermal switch input, Pin 4, is debounced (see figure 1).
Relay control output, Pin 2, is disabled when the battery
voltage, VBatt, is applied. Relay control output follows the
conditions of the switch, Sth, only when the ignition is
switched-ON. This is possible only after the debounce
time, t3. In this case Pin 5 is connected to Pin 7.
Timing waveforms are shown in figure 4. Total delay
time, td, is the sum of all ON-pulses caused by the thermo-
static switching. This can run down at once or in parts. If
Sth (Pin 4) is open, the oscillator is stopped (switched-off)
internally, but when it starts (Sth closed), the delay time,
td, starts running again. In case of renewed switching of
ignition, the counter of the delay time is reset.
