Features
1. Description
The bipolar integrated Atmel
ated automotive flasher modules and makes it possible to detect the outage of flasher
bulbs on the vehicle itself and also on a trailer.
Vehicles with a trailer hook are equipped with additional pilot lamps in the dashboard.
Atmel ATA2069 is off (i.e., the relay is deactivated) as long as the flasher switch (at
contact +49a) is open. As soon as this switch is closed, the IC starts reliably with the
bright phase.
There are two thresholds integrated: one threshold is defined to be 21 + 10W and is
designed for the lamp outage detection of 1 of 2 lamps. If the current is below this
threshold, the IC switches to frequency doubling, just like the standard flashers (e.g.
Atmel U2043B).
The other threshold is defined to be 42 + 10W and is designed for the outage detec-
tion of 1 of 3 lamps; if this happens, the additional trailer pilot lamp is switched off, but
there is no frequency doubling. 50 ms after the start of the bright phase, the compara-
tor measures the voltage drop at the shunt and latches this value for the rest of the
bright phase. The output of this pilot lamp (pin 8) is short-circuit protected against
GND. In case of a short circuit the external transistor is switched off after 52ms for the
rest of the current flasher cycle, but it is enabled again for the next cycle.
