Description

The bipolar integrated circuit U6044B, U 6044 B, 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 cool-off process. In addition, an air-conditioning contact U6044B can switch on the radiator fan at any time.
