com Description The integrated circuit 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.
