PDOT-DIS
Preliminary Data Sheet
Power Down Overtemperature Disable
PDOT-DIS = 0
PDOT-DIS = 1
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 must be switched
manually to PDH mode and then in the mode as
desired (otherwise the OTEMP bit in INTREG1 will
not change back to 0).
When overtemperature is detected, the
SLIC-E/-E2/-P does not 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 that keeps the SLIC-E/-E2/-P temperature
below the upper temperature limit.
The OTEMP bit in INTREG1 changes back to 0 if the
SLIC temperature is below the threshold again.
The INT registers may be locked in addition if
OTEMP-M = 0.
Note: Transients on Tip/Ring can cause false
overtemperature alarms, because the OTEMP
signal is not deglitched. To avoid this situation
it is recommended to switch off the automatic
power down on overtemperature (PDOT-DIS
= 1)
overtemperature handling in the interrupt
service routine.
