Description
The integrated circuit ATA6140 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 the ATA6140 can be connected
to the battery directly.
