Running the detection mode

9.4

Condition in order to get a successfully detection condition

Table 13. Detection condition (VDD = 3.3 to 5 V Temp. Range -40 to 85°C)

Open line or output

SW-1 or SW-3b short to GND

detected

==> IODEC ≤0.5 x IO

No error

detected

==> IODEC ≥ 0.5 x IO

SW-2 or SW-3a

Short on LED or short

to V-LED detected

==> VO ≥ 2.4 V

No error

detected

==> VO ≤2.2 V

Note:

Where: IO = the output current programmed by the REXT , IODEC = the detected output

current in detection mode.
