Product Description

 

The integrated circuit L2044G (analog U2044B) is used in relay controlled automotive flashers. With two output stages each side of the vehicle is controlled separately. A left and a right direction indicator input with only a small control current makes switch contacts for small loads possible.

 

The separate hazard warning input simplifies the construction of the hazard switch. Lamp outage is indicated by frequency doubling during direction mode. Thanks to the extreme low current consumption L2044G can be connected to the battery directly. The IC can used for 24V circuit and control LED.
