1. 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 con-

nected to the battery directly.
