exceeded. If the second threshold is exceeded the SCR is enabled (only if the
PassFETctrl bit is set to one) which allows the external power switch to latch off, and
can only be restarted by removing and reapplying power. Twarn is cleared using the
W1TC procedure.
No I
the Twarn bit is reported on the Address0/Fault_L pin. The value of PassFETctrl is
determined by the SDA/SCR_Enb pin, which is read at powerup.

SCL/CLIP_L pin. The pin is pulled low during a clipping event (assertion level low).
DAC Enabled: To handle the case when the DAC is in use and to meet the requirement
of a physical clipping signal, the clipping signal is brought out to the Addr0/Fault pin
I
the qualified VDS of the active FET exceeds the first threshold, at the same time the
IoutTrip bit is set. If the second threshold is exceeded the current is cycle-by-cycle
limited by switching the FET's off after few microsecond. If the cycle-to-cycle limitation
is present for more then 4 cycle the SCR is enabled (only if the PassFETctrl register is
set to one) and the external FET are tristated. In case of the SCR is disabled the
external FET are not tristated and the limitation still going. The register is cleared by the
W1TC procedure.
No I
