IX6R11 HALF BRIDGE DRIVER Evaluation Board
Features
• Single chip for driving high/low side MOSFETs /
IGBTs
• High to low side isolation of 600V
• Common-mode dv/dt immunity of greater than
50V/nanosecond
• Undervoltage lockout
• Optimized power circuit layout
• High side bootstrap supply
• Sockets for freewheeling fast recovery diodes
(FREDS)
• Flexibility of power level utilization
• 5V compatible HCMOS input logic with hysterisis
• Protection from cross conduction of the half
bridge
• Simple, fast and low cost means of evaluation
and design
• Option for using IXDP630 with RC oscillator or
IXDP631 with crystal oscillator for improved dead
time accuracy.
• Three phase operation with the ability to attach
additional slave driver boards.
Introduction
The EV6R11 KIT implements a single power phase-leg
circuit on a double-sided PCB, using the ISOSMARTTM
HALF BRIDGE DRIVER CHIPSET - IX6R11and IXDP630
dead time generator. This evaluation board includes an
assembled and tested PCB with two power devices. Just
follow the instructions in this document and connect the
board to the load and power.
Any power circuit is layout sensitive. The layout of this
PCB is a proven, working layout. The designer is invited
to duplicate this layout in his system, following the
evaluation of the driver chipset.
Most systems vary in their power level requirements and
therefore the power devices used. Due to this fact and
fluctuations in availability of power devices, the kit will not
always include the same power devices. The designer is
encouraged to use the power devices that are required for
his system. The devices that are enclosed serve only for
initial evaluation.

EV6R11 KIT
ASSEMBLY:
Figure 3 is a complete schematic diagram of the
design kit. This schematic indicates an applica-
tion using MOSFETs. When IGBTs are used,
freewheeling diodes (D2&D3) are typically
added.
To operate the PCB, simply solder the included
MOSFET power devices and C9 or install de-
vices specific to your application. Note gate drain
source pin orientation of power devices when
installing on the PCB. C9 has not been installed
due to its high profile and possible lead damage.
NOTES:
up. Jitter is then produced as drive signal 'On'
time overlaps into dead time. A practical limit in
values are soon reached with timing compo-
nents R3 and C5 as they are adjusted to com-
pensate for the reduced period in drive frequency.
It is possible to 'overdrive' the IXDP630 with an
external clock signal applied to pin 10 to reduce
dead time even further than what is possible with
R3 and C5. To do this, remove R3, C5 from the
board and install a 50 Ohm load resistor at
position R10. Solder pads have been provided
at R10 to solder the ends of a coax cable directly
to the board. The IXDP630 can be driven in
excess of 50MHz.
a) The ICs and Power devices are static sensi-
tive and require special handling.
b) Use any power device that is suitable for your
application. The PCB was designed to accept
devices with TO-247 or TO-264 packages. Two
IXYS power devices are included in the kit. D2
and D3 are required only if Q1 and Q2 are IGBTs,
and thus are not included in the kit. (A recom-
mendation for D2 & D3 is in the Bill of Materials).
c) Use any convenient method of interconnec-
tion at LS_GND, Q1-D, Q2-S, DC_BUS. The
hole spacing is 5.08mm and will fit most com-
mon terminal blocks. (A recommendation for a
connector that the PCB will accept is in the Bill
of Materials and is available from Digi-Key
among other sources).
d) For half bridge applications, insert a jumper
between Q1-D and Q2-S.
e) The gate resistors, R1 and R2, will depend on
the power device size that is used. 5.11 Ohm
resistors are installed and should work for most
applications.
g) The IXDP630 dead time generator is a 5V
HCMOS device. The addition of the IXDP630 on
the evaluation board is in part for convenience in
providing dual complementary drive signals. The
IXDP631 is a performance extension of the
IXDP630 and can be added as desired by the
user. However there is no part number available
for a IXDP631 loaded evaluation board and the
user must request IXDP631 samples separately.
Please note that threshold levels must be ob-
served when selecting the front end logic Vdd
supply voltage. To increase threshold level flex-
ibility, this PCB incorporates a level translation
circuit with Q3 and Q4. As configured, a three
terminal +5V regulator, U1, supplies power to
the IXDP630 and translator circuit which implies
that Vdd should be greater than 8V to prevent
regulator drop-out. Please note that this is only
one way to configure the board and was chosen
to provide a fast, easy way to get started during
the design stage.
f) IXDP630 dead time is provided by timing
components R3 and C5 and is fixed at roughly
1 microsecond. See the IXDP630 data sheet for
calculation and modification of the dead time
value. It must also be noted that dead time starts
to impact drive signals as drive frequency goes
