Logic input signal referenced to
LG (logic ground). In the
IXBD4410. A "high" to this pin
turns on its gate drive output and
resets its fault logic. A "low" to
this pin turns off the gate drive
output. In the IXBD4411 this pin
is not used and should be
connected to its ground (LG).

(IXBD 4411)
Logic input signal referenced to
LG (logic ground). In the
IXBD4410, this signal is
transmitted to the IXBD4411
"high-side" driver through pins 4
and 5 (T- and T+). A "high" to
this pin turns on the IXBD4411
gate drive output and resets its
fault logic. A "low" to this pin
turns off the IXBD4411 gate
drive output. In the IXBD4411
this pin is not used and should
be connected to its ground (LG).

Transmitter output complemen-
tary drive signals. Direct drive of
the low signal transformer, which
is connected to the receiver of
the chipset's companion device.
In the IXBD4410, this signal
transmits the on/off command to
its companion IXBD4411. In the
IXBD4411, this signal transmits
the fault indication to its
companion IXBD4410 driver.
Receiver input complementary
signal. Directly connected to the
low signal transformer, which is
driven by the chipset's compa-
nion device. In the IXBD4410,
this input receives the fault
indication from its companion
IXBD4411 driver. In the
IXBD4411, this input receives
the on/off command from its
companion IXBD4410 driver.

Low/high side fault output. In the
IXBD4410, this output indicates
a fault condition of either device
of the chipset. A "high" indicates
no fault, A "low" indicates that
either overcurrent,V
DD
or V
EE
under-voltage occurred. In case
of overcurrent, this output will
remain active "low" until the next
input cycle of the respective
driver. In case of under-voltage,
this output will remain "low" until
the proper voltage is restored.
The IXBD4411 does not have a
FLT output,and its pin 8 should
be tied to LG

(IXBD 4411)
Current sense or desaturation
detection input. This input is
active only while the OUT pin is
"high" (on). When the OUT pin is
"low" (off) this input is pulled to
ground through a 70
Ω
resistor.
Any voltage at this pin above the
threshold of .3 V typical, will turn
the output (pin 15) off. This pin is
used for power device
overcurrent protection.

15 Gate drive output. In the
IXBD4410 this output responds
to the INL signal. A "high" at INL
will turn it on ("high"), a "low" will
turn it off ("low"). In the
IXBD4411, this output responds
to the transmitted signal from the
companion IXBD4410. A "high"
at INH of the IXBD4410 drives
will turn it on ("high"). A "low"
will turn it off ("low"). This output
will turn off ("low") also in
response to any fault condition.
