8.5 Error Detection Functions
8.5.1
Open-LED Detection
The AS1109 open-LED detection is based on the comparison between V DS and V THL . The open LED status is aquired at the rising edge of
OEN and stored internally. While detecting open-LEDs the output port must be turned on. Open LED detection can be started with 1 clock pulse
during error detection mode while the output port is turned on.
Note: LEDs which are turned off at test time cannot be tested.

The AS1109 shorted-LED detection is based on the comparison between V DS and V THH . The shortened LED status is acquired at the rising
edge of OEN and stored internally. While detecting shorted-LEDs the output port must be turned on. Shorted-LED detection can be started with
2 clock pulses during error detection mode while the output port is turned on.
For valid results, the voltage at OUTN0:OUTN7 must be lower then V THH under low-current diagnostic mode operating conditions. This can be
achieved by reducing the V LED voltage or by adding additional diodes, resistors or LED’s.
Note: LEDs which are turned off at test time cannot be tested.

Thermal protection for the AS1109 is provided by continuously monitoring the device’s core temperature. The overtemperature status is aquired
at the rising edge of OEN and stored internally.
