IXBD4411
The IXBD4410/IXBD4411 ISOSMART
chipset is designed to control the gates
of two Power MOSFETs or Power
IGBTs that are connected in a half-
bridge (phase-leg) configuration for
driving multiple-phase motors, or used
in applications that require half-bridge
power circuits. The IXBD4410/
IXBD4411 is a full-feature chipset
consisting of two 16-Pin DIP or SO
devices interfaced and isolated by two
small-signal ferrite pulse transformers.
The small-signal transformers provide
greater than 1200 V isolation.
Even with commutating noise ambients
greater than ±50 V/ns and up to 1200 V
potentials, this chipset establishes
error-free two-way communications
between the system ground-reference
IXBD4410 and the inverter output-
reference IXBD4411. They incorporate
uonvedrecruvrorletangt eorVdDeD soartuVrEaEtilooncksohuuttadnodwn
to protect the IGBT or Power MOSFET
devices from damage.
The chipset provides the necessary
gate drive signals to fully control the
grounded-source low-side power
device as well as the floating-source
high-side power device. Additionally,
the IXBD4410/4411 chipset provides a
negative-going, off-state gate drive
signal for improved turn-off of IGBTs or
Power MOSFETs and a system logic-
compatible status fault output FLT to
indicate overcurrent or desaturation,
and undervoltage VDD or VEE. During a
status fault, both chipset keep their
respective gate drive outputs off; at
VEE.

INL 2 Logic input signal referenced to
NC 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).
No Connection (IXBD 4411)
INH 3 Logic input signal referenced to
NC 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).
No Connection (IXBD 4411)
T- 4 Transmitter output complemen-
T+ 5 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.
R- 6 Receiver input complementary
R+ 7 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.

Sym. Pin Description of IXBD 4410/4411
FLT 8 Low/high side fault output. In the
NC IXBD4410, this output indicates
a fault condition of either device
of the chipset. A "high" indicates
no fault, A "low" indicates that
either overcurrent,VDD or VEE
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
No Connection (IXBD 4411)
IM 9 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 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.
KG 10 Kelvin ground. This ground is
used as Kelvin connection for
overcurrent or desaturation
sensing.

OUT 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.
