ADVANCE DATA
It must be noted that while in Soft Shut Down,
both Under Voltage fault and external Shut Down
(SD) are masked until the end of SSD.
Desaturation protection is working independently
by the other entire control pin and it is disabled
only when the output status is off.

4.2.2 Fault management in multi-phase
systems
In a system with two or more gate drivers the
IR2214 devices must be connected as in figure 15.
SY_FLT.
The bi-directional SY_FLT pins communicate
each other in the local network. The logic signal
is active low.
The device that detects the IGBT desaturation
activates the SY_FLT, which is then read by the
other gate drivers. When SYS_FLT is active all
the drivers hold their output state regardless the
input signals (H
, L
) they receive from the
controller (freeze state).
This feature is particularly important in phase-
to-phase short circuit where two IGBTs are
involved; in fact, while one is softly shutting-down,
the other must be prevented from hard shutdown
to avoid vanishing SSD.
In the Freeze state the frozen drivers are not
completely inactive because desaturation
detection still takes the highest priority.
SY_FLT communication has been designed for
creating a local network between the drivers.
There is no need to wire SY_FLT to the controller.
FAULT/SD
The bi-directional FAULT/SD pins communicates
each other and with the system controller. The
logic signal is active low.
When low, the FAULT/SD signal commands the
outputs to go off by hard shutdown. There are
three events that can force FAULT/SD low:
1.
Desaturation detection event: the
FAULT\SD pin is
latched
low when SSD
is over, and only a FLT_CLR signal can
reset it.
