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
undervoltage V
DD
or V
EE
lockout and
overcurrent or desaturation shutdown
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 V
DD
or V
EE
. During a
status fault, both chipset keep their
respective gate drive outputs off; at
V

.
