SLICOFI-2x Command Structure and Programming
When overtemperature is detected, the SLIC is
automatically switched into Power Down High
Impedance mode (PDH). This is the safe operation
mode for the SLIC-E/-E2/-P in case of
overtemperature. To leave the automatically
activated PDH mode, DuSLIC has to be switched
manually to PDH mode and then in the mode as
desired.
When over temperature is detected, the SLIC-E/-E2/
-P doesn’t automatically switch into Power Down
High Impedance mode. In this case the output
current of the SLIC-E/-E2/-P buffers is limited to a
value which keeps the SLIC-E/-E2/-P temperature
below the upper temperature limit.
from the transmit path directly (UTDX-SUM = 0) or
uses the data from the sum signal of receive path
and LEC (if LEC is enabled) (UTDX-SUM = 1).
from the LEC output, if the LEC is enabled (LEC-EN
= 1), otherwise the UTD unit uses automatically the
transmit signal.
