Observe precautions for handling. 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 connected to the battery directly. Rev. 4560E–AUTO–09/05 Figure 1-1.

Short Circuit or Overload Detection Delay Direction mode: 100 ms during the first bright phase, 50 ms during all following bright phases Hazard mode: 100 ms during all bright phases In case of overload the relay output switches off (not stored) 9. Bulb Outage Detection The detection of bulb outage takes place during the bright phase. There is a delay time of typically 128 ms before ATA6140 measures the bulb current with a debounce period of 5 ms. After this time the inrush current dropped significantly. Application hint: It has to be considered that a slow relay contact may shorten the inrush current decay time and too high current would be measured and falsely an outage may not be detected. If operated with low supply voltage (e.g., 8V) the relay speed could be even slower. 6 ATA6140 4560E–AUTO–09/05 ATA6140 10.
