Phase three: “resuming to normal mode”
The sequence for re-entering in normal mode is showed in the following table and diagram:

Note:
For proper device operation the “entering in detection” sequence must be follow by a
“resume mode” sequence, isn’t possible to insert consecutive equal sequence.

Note:
Error detection conditions
VDD = 3.3 to 5 V temperature range 25 °C.
Table 14. Detection condition
SW-1 or SW-3b
Open line or output
short to GND detected
==> IODEC 0.5 x IO
No error
detected
SW-2 or SW-3a
Short on LED or short
to V-LED detected
==> VO 2.5V
No error
detected
==> IODEC 0.5 x IO
==> VO 2.2 V
Where: IO = the output current programmed by the REXT,
IODEC = the detected output current in detection mode.
