Chipset Overview
This ISOSMART
integrated circuits providing isolated
high- and low-side drivers for phase-
leg motor controls, or any other
application which utilizes a half bridge,
2- or 3-phase drive configuration. They
consist of two drive control inputs (INL
and INH) for two Power-MOSFET/IGBT
gate-drive outputs. Both inputs operate
from a common ground and are
activated by HCMOS compatible logic
levels. The low-side output operates
near input ground, while the high-side
output operates from a floating ground
that is nominally the source connection
of the high-side phase-leg power
device. Both outputs typically provide 2
A of transient current drive for fast
switching of the phase-leg power
device.
IXBD4410/IXBD4411
The full featured ISOSMART
chipset incorporates a IXBD4410 as
the low-side driver (Fig. 3) and a
IXBD4411 as the high-side driver (Fig.
2). When input "INL" is set to a positive
logic level, the low-side gate output
goes high (turns on); when "INH" is set
to a positive logic level, the high-side
gate drive output goes high. The high-
side IC is isolated from the low-side IC
by a magnetic barrier, across which the
turn on/off signal is transmitted to the
high-side gate drive. The IXBD4411
fault signal is also transmitted back to
the IXBD4410 driver via these
transformers. This isolation only
depends on the low cost communica-
tions transformer, which is designed to
withstand 1200 V or more.
There are two magnetic transmission
channels between the low- and high-
side IC's for bi-directional communi-
cation. One sends a signal from the
low-side IXBD4410 IC up to the high-
side IXBD4411 IC and the other sends
a signal back from the high-side to the
low-side IC. The signal that is sent up
controls the IXBD4411 gate-drive
output. The signal sent from the
IXBD4411 back to the IXBD4410
indicates a high-side fault has occurred
(overcurrent, or under-voltage of the
high-side +power supplies). This is
detected at the IXBD4410 driver and
sets "FLT" pin low, to indicate the high-
side fault.
The fault signal that is returned from
TM
chipset is a pair of
TM
driver
