U6049B
Radiator Fan Control Timer
Description
The bipolar integrated circuit, U6049B, is designed as a
radiator fan control timer. After the ignition is switched
off, the thermal switch of the engine can activate the ra-
diator fan via relay for a preset period to support the
cooling process.
Features

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
